I don’t know what’s happening?!😳😕

So, I’m usually super regular and get my period every 28 days but I just had my period from October 22nd to the 26th and then 6 days later on November 1st I started bleeding again. I started the bleeding one night after having sex with my husband. It wasn’t necessarily rough either?? This is very abnormal for me. I talked to a lady at a clinic and she suggested maybe he busted something called a polyp. I don’t know thought because I’m still bleeding and it’s been 7 days. I would have already been to the doctor but I don’t have insurance currently and can’t afford another outrageous bill if it’s nothing to worry about.😕
