Ok so, ovulated 2 weeks ago. A week ago I began bleeding, at first I thought this might have been implantation but it became heavier. Not quite Af and only lasted 2 days (af usually) so I thought, sadly that it may have been a chemical pregnancy. Been so tired all week, I mean 9hours each night and a 3 hour nap in the day tired, so toot a test yesterday (Af would have normally been due today) and got a BFN. Just randomly took a cb opk and got a static smiley? So confused!
