Menstrual problems

Kat
I hate my period!!!its so inconsistent , since I got it when i was 16 i've never been regular i am 25 now . Been ttc for about 1 year now and nothing , i was on the pill for a good 3-4 months after having a vaginal hemorrhage back in july of 2015 to control and regule my period . I have not seen my obgyn since then! I want to get pregnant!!
