okay ladies i have a tmi question. its 4 am here and i have no one to call. so for the last 2 or 3 times i have peed tonight i have had little bloody mucus like stuff floating in the toilet afterwards. no blood on the toilet paper. just the stuff in the toilet. ill add pic in comments for reference. but what is it? im 35 weeks pregnant. and could this be from being intimate? should i be concerned? back backs been hurting. im not currently contracting. but my vagina has been sore. i have had contractions randomly off and on lately but not for long periods. except 3 days ago when it lasted for 2 hours. i drank lots of water and laid on my side and it finally stopped.
