I have PCOS and I had my first IUI 2 weeks ago (8/2). I used Follistim to ovulate and the Ovidrel trigger shot on Sunday night. I am also on progesterone suppositories so I haven't started a period. I got a BFN on Monday and Tuesday morning (Days 14 and 15). I have read online that some people don't get a BFP until day 18 or later. Has that happened to anyone here? Am I holding out hope for yet another failed month?
