Pregnancy test question...?

Question

I have been having some odd symptoms. I was spotting, cramping, having headaches, and lower back pain. I went to a clinic since I was feeling so horrible and tired. They thought that I could possibly be pregnant. It is possible that I could be..but it has only been about a week. The clinic tested me and it came back negative but I had a urinary tract infection. I read somewhere that a woman had a UTI show up but a negative preg. test and found out a few weeks later that she was. They said that a urine test can show at day six if your pregnant but I've never heard of one showing that early. I was just wondering if it is really possible to detect pregnancy this early... I was pretty dissapointed when they said I wasn't so i'm hoping that there is still a chance.

I wanted a blood test done but they didn't give me one since I was just at a clinic at my college. They gave me a urine test and sent me on my way...even though I told them that I had sex only a week before...but they didnt really listen to me

Answer 1

There are some pregnancy tests that will show that early. The health department told me they could test for pregnancy on their urine tests 10 days after sex but a blood test will show if you are pregnant or not 7 days following conception.

How soon can I test? Well, first you gotta know how the test works. Briefly: the home pregnancy test (HPT) works by detecting a hormone called human chorionic gonadotropin (hCG.) When an egg is fertilized, it takes about 6 to 12 days to implant in the uterus, and then it begins to secrete hCG. It takes another day or two for enough hCG to build up and make its way into your pee. So, generally speaking, the earliest you can expect a positive HPT is 8 days past ovulation ("DPO") and the latest would be about 16 DPO. It is possible to get a positive test earlier or later, but not as common. In my experience, if you use a sensitive "early" test (anything that detects 25 mIU/mL of hCG or less) you can test around 12-14 DPO and feel reasonably secure with your results (the later you test, the more secure you can feel in its accuracy.)

If you do not chart or monitor your fertility in any way, and you think you may have conceived, you should wait 19 days (or longer) after having sex to test. Why 19?! Sperm can live approximately 5 days in the proper environment; if the sperm managed to live until you popped an egg, the actual conception could have taken place several days after the sex act that got the sperm there. To make sure you're not testing too early, assume the sperm had very long lives (5 days is considered a very long sperm life) and that conception occurred then. Then allow 14 days for the embryo to implant and develop enough hCG to show up on a pregnancy test (96% of pregnant women will test positive by then.)

Note: some HPT's say "test 5 days before your period is due!" or some such thing. Please note they are assuming a textbook 28-day cycle, with ovulation on Day 14. "5 days before your period is due" thus really "translates" to 10 DPO.

Essentially, you should remember that your high school biology textbook was WRONG. NOT all women have 28-day cycles and NOT all women ovulate on Day 14. For more info on this type of thing, see the Fertility Info section.

Here's an example. This is the textbook-perfect 28-day cycle with ovulation occurring on day 14 (in pink.) 10 DPO and later are reasonable days for testing (in green.) This is the cycle the HPT companies have in mind when they say "test 5 days before your period is due!"



Well, not everyone's body works this way. Here's another 28-day cycle-- but this one has ovulation occurring a little bit later, still well within the normal range. Watch what happens to your (green) testing opportunities!



All of a sudden, "5 days before your period is due!" is way too early for you to expect a positive test! (I tend to ovulate later myself, so by the time the "gold standard" of testing at 14 DPO is applicable, my period is already 3 days late! I needed to use an "early detection" test on the first day of my missed period. A "regular" test would probably have been negative-- even though my daughter is living proof that I was, indeed, pregnant ;)

Of course, it works in reverse, too. If you're an early ovulator, you're lucky! Check it out:



In this scenario, you could test even sooner than 5 days before your expected period.

Ultimately, it's important to remember that implantation is a variable thing. You may be able to detect a pregnancy very early on, but then again, you may not! If you can't, don't despair. http://www.peeonastick.com

Answer 2

It's possible that it's just too early. I did one when I was probably about a week along and it was negative, then about 3 weeks later, it was positive. Incidentially, I had to pee alot even before I found out...I thought I had a UTI or another kidney stone. Frequent urination can be a sign of early pregnancy.

Just take care of yourself and even though the wait will be hard, try it again in a few more weeks.

Answer 3

If the clinic gave you a blood test and it came back negative, then the chances of you being pregnant are slim, but you can wait a week or so and have another one done.

Answer 4

its possible, some people dont find out they are pregnant until at least 6 weeks gone which is usually when youre about 2 weeks late. retest in a few days if its still negative then go to your doctor and get a blood test done.

Answer 5

It's very possible that you may be pregnant because not all the time do women show up in pee test or blood test but some doctors might say it can't happen that way but they be guessing. I know from friends that you can be pregnant even though test don't show. good luck to you...

Answer 6

mine came up positive 2 days before my period was due, it was pretty light though, I used a first response. some of the cheaper tests don't work as well as the more sensitive expensive ones. I recommend waiting til you are due, or almost due and retest with a name brand test.

Answer 7

only blood can read up at day six but even that is rare urine wont read until your period is late or due
