How soon can I test for pregnancy? My period was due 2 days ago on (3/10) and had intercourse on (3/08).?

Question

I'm experiencing some lower back pain, like a cramping feeling. I'm concerned if this is normal. Do I have to wait until next month when my period would be due?

Answer 1

It's certainly not going to hurt to test now. Presumably, though, if you were going to conceive, you would have done it earlier in the month, near the middle of your cycle, rather than two days before your expect menstrual period.

Answer 2

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.)

Answer 3

If your period is due on 3/10, you would have ovulated on Feb 24 based on a 28 day cycle.

I think the lower back pain and cramps are from an upcoming period, not from being pregnant.

If you want to get pregnant, you ovulate about 14 days past day 1 of your period.

Answer 4

Cramps etc are probably from your period coming on because if you are pregnant you shouldn't be feeling those symptoms from being pregnant this early.

The commercials for the tests say that they can detect pregnancy 5 days after your missed period. Remember you can have an false preg test and still be pregnant but you cant have a positive one and not be pregnant

Good Luck and Possible Congrats

Answer 5

If you conceived, it would've been about fourteen days before you were supposed to get your period because that it is when you ovulate. However you can take a pregnancy test the first day of your missed period, so if you were to take one now it would most likely be accurate. The lower back pain can also be a sign of your oncoming period, I get that every month.
Good Luck!!

Answer 6

You could test today but it might not be accurate until 14 days after conception (the 22nd) That's because the HCg levels are really low in the first 2 weeks you're at risk for a false negative. You could go to the doc for a blood test, but you're wasting your money on a home test.

Answer 7

No, you don't have to wait. Pregnancy makes for instant hormone changes. The cramping feeling might be your late periodon the way. Take a test if you want to know ASAP.



Good luck :)

Answer 8

NOW! I took my test right when my period was 2 days late. (I had taken it 2 weeks earlier but it came back negative, but I just knew I was so I waited longer) Try to do it right in the morning, because after you hold your urine all night it is the strongest and will have all the right hormones to let ya know.

Call your gynecologist.
