Hello ladies, so today I found some blood when I wiped and it hasn't stopped.i went to the ER and was there ALL DAY.and was told my hcg levels were low for being 8 weeks.but everything else looked fine and don't know why I'm bleeding.so I'm basically in bed rest for the week, have to go take blood test every 3 days, and just wait.My fiancé Nd I think it was intercourse.anyone else expirienced anything similar? I am terrified and really want my baby to be ok
