Has anyone taken any fertility pills to help ovulate and gotten pregnant? »

How long do fertility drugs stay in your system and give a false positive result?

I did IUI 9 days ago, I know that I'm not supposed to take a pregnancy test as the fertility drugs that I was taking will give me a false positive, I'm just wondering how long it stays in your system. The last time I did IUI I took a test 14 days after and it was negative. 9 days in I'm going out of my mind with stress and worry! Can anyone help?

Like most things in life, it depends. Here it depends on the HcG shot (that you presumably took for the IUI which can cause false positive) and how much did it elevate the HcG levels at that time. The good news is that hcG has a fairly short-life (average 36 hours or so), so it does quickly get out of your system. By 10 dpo, it is very likely that it is below 20 (minimum levels for most HPTs).

However, I think 14 days is the standard protocol to wait after hcG shot before testing.

perhaps test at 12 dpo, and if it is faint positive, re-test again at 14dpo, so see if it has changed to a BFP! Good luck.

    It depends on the drug. Your doctor should have told you how long to wait. But the 2 week rule is a good place to start.
