did this happen after a BM? Sorry if a TMI question but this happened to me very early in my pregnancy. had bleeding like you are describing after a BM.
Lots of times bleeding is fine. Subchorionic hematomas are often the cause and it's RARE for those to cause a loss. It's not impossible though.. that's how I lost my triplets.. but it happens in like 2% of cases.
I hope this is nothing. I know it's hard after what you've been thru before but try to stay positive. I've heard/read that some girls bleed in early/throughout their pregnancy. U r in my prayers that this is nothing serious!
