I had my egg retrieval 12 days ago. I had 2 healthy embryos implanted day 3. I am currently 12 days past ovulation (or retrieval) and i woke up this morning to a little dry blood in my underwear... I am on Progesterone so it isn't likely it is AF... Could it be implantation bleeding this late?? Confused! I have my BETA on Tuesday morning... I am praying this works! TTC since July 2014...

Is it normal to have implantation bleeding 12dpo??
