Could my period be the infertility factor?

Patient: My question is, i have irregular periods, i am 20 years old, and do have unprotected sex with my partner of now a year, when i do get my period, it is extremely heavy for the first couple of days. Also i get blood clots that come out during these days as well, i was wondering if this could be the reason i cannot get pregnant? and if it is something i should get checked out by a doctor?
