Soo annoyed ?

I started my period November 10th. On the 18th and 19th, my period stopped until the 21st, I started bleeding again. I stopped bleeding on the 22nd. Me and my fiancè had sex the 22-26 and after we had sex, I went to the bath room, wiped and I had started my period, again! I've had two heavy periods this month. That neve happens to me.. Should I go to the doctor?
