Preggies, PLEASE stop confusing me. Can someone that knows the facts help me with this...help!!!!!?

Question

Ok, I asked a question earlier about how far along I was, and if ultra sounds are more accurate. I'm 11.5 weeks...my due date is June 24th. That is N0T going by my LMP, but my due date was given to me by my ultra sound at 9 weeks. One girl stated that I'm 11.5 weeks so I conceived 13.5 weeks ago. WHAT IS SHE TALKING ABOUT? And then, another girl said that if you go by ur LMP 11.5 weeks was ur LMP, so techinally I'm 9.5 weeks(the baby) Then, there were a few more comments that were made that just don't make sense. I guess I will re-word this whole question. If I am 11.5 weeks...and my due date is the 6-24 then can the doctor be off by 3 weeks? The reason I'm asking is because I had to sexual partners in the month of September. Yes, I know, DNA test are the smartest way, but It's either my boyfriends, or a friend. I slept with my friend Sept 16th (just once) and my boyfriend almost every other weekend. Someone please help..and no mean answers sayin I'm a slut, I already feel that way.

Answer 1

Okay, here goes. Ultra sounds in early pregnancy are extremely accurate. If your ultrasound results state you are 9 weeks along, go by that. The doctor counts your pregnancy weeks from the beginning of your last period. So, technically, you baby is two weeks younger then how far along you the mother is. For instance, you are eleven weeks pregnant, and your baby is 9 weeks old. The reason for this is you don't ovulate until a few weeks after your period, so techincally at the time of conception your doctor already considers you two weeks pregnant. Do not go by any other charts to find your due date, the ultrasound is by far the most accurate. If your doctor told you that you are 11 weeks pregnant, then you would have concieved 9 weeks ago. Any questions just e-mail me. I hope this helps.

Answer 2

Sorry this is so confusing for you. What I am fairly certain of is that fact that early ultrasounds are not very accurate for judging due dates. I have four children, three of which were very difficult pregnancy that required several ultrasounds. I know this doesn't help you, and I am sorry.

Your doctor should repeat an ultrasound again at 20 weeks that will help provide better measurements and provide you with a better more accurate date. But, you have to remember that babies are very rarely born on the days that we predict they will be born on, so things may be off even still.

I would say that at this point in time, your best bet is to go by your LMP and then do the proper test after the baby is born.

Hope this all works out for you.

Answer 3

It's possible the doctor is off by 3 weeks. If you ovulated late or early that would effect it. For the sake of your question if we imagine you ovulated exactly 14 days into your cycle and your doctor's due date is right, then you can count back 9 1/2 weeks and that would be the approximate date of conception. For some reason when you get pregnant they count the week of your LMP as your first week of pregnancy, so technically when you conveive you are 2 weeks pregnant. Hopefully that gives you a good time period to look at and know who it was. If you want a better explanation of the wacky date thing, you can borrow a copy of What To Expect When You're Expecting from the library. Because every women is different, you might not be able to know for sure until the baby comes. Good luck to you.

Answer 4

You need to go by your LMP not an ultrasound as they can be inncacurate but technically your LMP is innacurate as well. If you are familiar with your body's signals you can tell when you ovulated and that is more accurate than ANY doctors guess. If you have no idea when you ovulated then you are just going to have to wait for a DNA test becuase all women are different. The standard is 2wks. after your LMP is when you ovulate (in theory). So the one you slept with closest to that time is most likely the father. However, not all women are textbook. You could have ovulated a few days before or even a week after the standard ovulation time. So look at a calender and try to figure who was the closest but I'd just recommend a DNA test.

In the future keep sex inside of marriage and then you'll never have this happen again! My husband and his sister were both born under the same circumstances and to this day do not know who there fathers are and it is terrible for them. Think about your child next time instead of your own lusts.

Answer 5

Pregnancy "weeks" are calculated starting with the date of your LMP (about two weeks before you ovulate). If someone said you are 11.5 weeks and conceived 13.5 weeks ago, they've got it backwards. If you are 11.5 weeks, you would have conceived about 9.5 weeks ago (two weeks after your LMP, about on the probable date of ovulation).

Based on the numbers you've stated, you should have conceived somewhere around October 1st. You can find a date-of-conception calculator on the Internet. This is not a guarantee that your friend is not the father (depending on when in September you had sex with him).

Good luck to you!

Answer 6

The reason she might have said that you conceived 13.5 weeks ago if you're 11.5 weeks is slightly wrong.

The way they calculate how far along you are in your pregnancy, if they are going by your last perod, is that they count the weeks STARTING at the first day of your last period. In your case, your last period should have been 11.5 weeks ago - - meaning that you most likely conceived 9.5 weeks ago. So technically speaking, obviously, you're only 9.5 weeks, but doctors and midwives always count the pregnancy from the first day of the last period. This is compensated towards the end of the pregnancy - the actual length of a pregnancy is usually 38-39 weeks - - but because of the way that they calculate your prengnacy in weeks, they "say" that the average pregnancy is 40-41 weeks long. Hope that helps!

Answer 7

OK.. Your estimated conception date for your due date is October 1. That would take your friend out of the picture. Don't feel like a ****. A lot of women find themselves in this position. At least it is only 2 men. Could be 12. I am going to give you a link so you can see how I got the info. According to your due date your last period was September 17. I know it could be wrong but that is what you need to input to get your proper due date. Good luck and Congrats

Answer 8

It's always a possibility that the doctor could be two weeks give or take off on calculating your due date. However, if you had a sonogram to measure, I imagine it's not that off...Being three weeks off isn't unheard of but I imagine it's not.

If your due date is June 24th, then conception likely occured around October 1st. Keeping in mind that sperm can live in a woman's body for up to five days, I imagine that your friend is NOT the father and your boyfriend is.

Good luck and congratulations on the baby!

Answer 9

What I can tell you is that I went by the LMP, which was like may 11, and the round chart thing they have at the doctors said my due date was Feb. 14, the ultrasound gave me a due date of 5 days later. But I took the first due date she gave me and I ending up having my daughter on my due date of Feb. 14. And I had sex around may 18th. I don't know if that helps you at all. Good luck I hope you figure it out so you have your mind at ease.

Answer 10

There are some larger issues afoot here. Are you and your boyfriend going to stay together? Does your boyfriend know about your....uh....indescretion? Does all of that matter? Does the friend know it could be his? Will he support the child if it is? It is possible to get close with the ultrasound but I would believe that a 7 day variable is possible. If all parties are in agreement, do a blood test first. It is possible to determine paternity by simple phlebotomy. You may not need to go to the expense of the DNA test. If the blood test is inconclusive, then it may be necessary. If one does not know and you don't want them to know then some other action may be necessary. Good luck.
