If it came up negative 3 weeks ago, your not pregnant. You need to go to your doctor to find out why you're not having your period. You would be about 10 weeks along now, so 7 then. If you are pregnant it would have came up then....unless if you drank A TON of fluids, that might have diluted it enough to give a false negative, but being that far along, I really doubt it.

I would take it if you haven't drank so much liquid. I know how it is when you have a pregnancy test you can't wait to take it. If your period is that late then it will show up if you are.
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.)

If you lmp was dec 24 you should be far enough along where it shouldn't matter what time of day you take it. I would say that you would get the same result now that you would get in the morning. Good Luck and let us all know!!!!!!

They say the best time to test is in the morning. However, when I took my HPT's, I did them at different times of the day and they were all positive. So really, it's up to you. If you feel you can't wait then take it now. If you'll feel more comfortable in the morning then just wait.
Good luck!

If you havent had a period since dec. then you can take the test anytime of day...Your hcg level should be high enough for it to give an accurate result if you are preg...Good Luck!
