I'm so sorry this is hapenning to you. I'm Lisa (26) and DH is Marc (30). We've been together for 10 years, married now for almost 1 and TTC our first since July '08. And I'm sorry to introduce myself in this way, on such a topic...but here's my
My doctor told me not to test before AF is due (although I ALWAYS do, I can't stop myself!) because many early pregnacies never implant properly (something high, like 1 in 3 or 4 I think, not sure) and end up miscarrying naturally when AF comes. The problem now is that so many woman go through something similar as you described, where they are certain they got an BFP at 10 or so DPO but then get AF anyways and lose the embryo. Women never knew if they were pregnant that early before they put out the hypersensitive EPTs, so we are seeing this more now. She said it is very normal and there can be many different factors. I would go see my doc just in case, but it sounds like you may have gone through what I described. Or you might just be having a wierd cycle with AF too, we know how mean she can be sometimes! I hope you are able to get some answers and feel much better soon!
