We were doing injectible back to back IUIs August 18 and 19. We did the IUI on the 18th, but had to cancel the 19th because sperm was not good enough. We had sex on the 18th after the IUI. On Tuesday night (so I suppose 5dpo), I started spotting (brownish). Wed/Thur, red blood, though only when I go to the bathroom (only used a panty liner). Friday, scant blood again. I have been 29 days like clockwork my entire life, so this is too early for AF. We did a trigger on Wednesday the 17th, and an u/s on the 19th, so I know I ovulated 3 of the follicles (there were five). I had a lot of ovary pain and tender breasts too, those first few days. Does this count as AF and if so, how to restart the counting? We are going to take a break for a couple of months since this would have been our third IUI.
