I'd calm your doctor right away. It could be a number of things. One thing it might be is placental abrubtion. You never know and like everyone else said, better safe than sorry.
^i know i am worried and have been wondering i said a prayer for you and your baby
Bright red blood means call the doctor immediately! It might be nothing but better safe then sorry and bleeding and spotting are 2 very different things
I am 36 weeks and 37 in 2 days never experienced that. Call ur doctor and let her know. Some times it can happen after sex. I hope every thing turns out ok.
