what causes bleeding in the first trimester of pregnancy?
implantation bleeding can last longer than 12 days. it maybe considered something else after so long but that is what my dr. called it. i am not writing this because i think i know more than what wmd gave as an answer. however as a first time pregnant woman who has experienced light bleeding and cramping intermittently from week 3rd through my current 7th week i believe there is not enough information available about 1st trimester bleeding. i read so many articles like this that my head was swimming. i knew i wasn't having a miscarriage but what i was reading (all from credible sources btw) left me feeling like i was either doomed to miscarry or i would be bed ridden. when i went in for an ultra sound the nurse pointed out a little dark area between the amniotic sac and my uterine wall. she said that is where the blood was coming from. at 7w1d i was still experiencing implantation bleeding- it was still attaching in an area. she said it is common and everything was fine! i saw my little button wiggle and we heard a heart beat! baby measures perfectly. not every story is going to end quite as uncomplicated but i want women to have hope. there are a lot of answers- every pregnancy is different. talk to your dr. and never ever assume the worst. there is hope!
