Hi,I have a problem I need help with, I started my period on the 29 of dec and ended on the 3rd of jan,anyway I had sex on the 6 and started bleeding the next day,well spotting anyway when I wiped,the next day was the same thing but it was a little darker.. I was diagnosed with having endometriousus about 7 years ago but the signs and symptoms of it went away after having my daughter.. ive never had an abnormal paps and never had any kinds of std.. worst I've had is a yeast infection.. So could this just be from having rough sex or something else.. please reply..
