So I am looking for some advice. Don't worry I will be calling the doctor. I am bleeding and am 36 weeks pregnant. Not vaginally though. I accidentally scratched myself on the chest I guess. Don't even remember doing it. Next thing you know I look down and I have bled all over my shirt. Mind you this is the tiniest scratch. I can hardly see it. I tried to clean up the blood but it is literally gushing down my chest. We are on the third dressing but it just will not stop. It has been about twenty minutes now. My question is do any of you know if pregnancy causes thin blood, or could this be a symptom of something? Any advice is welcome right now and greatly appreciated!
