Hi ladies! after 16 months of seeing a fertility dr (grrr) I finally ovulated with medication , femara. I had two follicles that were released. Saturday, 14 dpo I started somewhat bleeding. It was brown almost black! and lasted until sunday night. Cramps were uncomfortable but not terrible. Now nothing? BFN on a digi this morning. My question is, is what could that be? AF has NEVER been that short and is always red. Can implantation bleeding happen that long after O? Is it possible that I had twins and could be losing 1 ? Faint BFP with FRER on Friday however I usually always have an HCG level around 6 so can't rely on that and Dr is on vacation!! Yikes, any thoughts? Thanks all!
