How many days past ovulation can you still get a -ve pregnancy test, but be pregnant?

Question

I think I ovulated about 23/24 Feb (have been off the pill since Sep 06 and periods are very long and irregular), but have done a few pregnancy tests this week and they are still -ve. I have slight nausea, backache and lower ab discomfort and just feel different (I'm hoping this isn't all psychological!). I know people produce different amounts of hcg in the early stages, but just wondering how far along you could feasibly still get a false -ve?

Answer 1

Best not to rely on the HPT's - get a blood test. It's the only way to be sure.

Answer 2

If you ovulated around 23/24 Feb you would have been a week overdue by now, so take a test now, anything earlier might be inconclusive. don't trust home tests, get a blood test, they are not wrong! Having the nausea and backache would not be anything to do with being pregnant, it would be tooooo early for symptoms like that. Good luck and keep trying .... I am also trying for my 3rd so no what u are going through

How quickly am i able to attempt? nicely, first you gotta know how the attempt works. right away: the homestead being pregnant attempt (HPT) works by ability of detecting a hormone called human chorionic gonadotropin (hCG.) at the same time as 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 yet another day or 2 for adequate hCG to strengthen and make its way into your pee. So, oftentimes conversing, the earliest you may assume an excellent HPT is 8 days previous ovulation ("DPO") and the hot may be about 16 DPO. that's plausible to get an excellent attempt earlier or later, yet no longer as undemanding. In my journey, in case you take advantage of a tender "early" attempt (some thing that detects 25 mIU/mL of hCG or a lot less) you may attempt round 12-14 DPO and experience quite take care of including your outcomes (the later you attempt, the more beneficial take care of you may experience in its accuracy.) in case you do not chart or exhibit screen your fertility in besides, and also you imagine you've conceived, you should attend 19 days (or longer) after having sex to attempt. Why 19?! Sperm can stay about 5 days in the right surroundings; if the sperm managed to stay until eventually you popped an egg, the certainly theory may have taken position a number of days after the sex act that were given the sperm there. to make certain you at the prompt are not testing too early, assume the sperm had very lengthy lives (5 days is seen a really lengthy sperm existence) and that theory exceeded off then. Then enable 14 days for the embryo to implant and strengthen adequate hCG to look on a being pregnant attempt (ninety six% of pregnant women human beings will attempt effective by ability of then.)

Answer 4

Well ...the home pregnancy tests these days are very accurate within a 24-48 hours after becoming pregnant. At this point if you are still coming up negative and you miss your next period have a doctor check you for a tubal pregnancy or an ovarian cyst.

Answer 5

You need at least a five weeks period after ovulation for HCG to register but it can happen sooner and can also go further back. On the other hand your period should stop and that you know after at least 26 days so wait at least two more week before testing HCG look for an absent period first.
