Am I broken?!

Yes I have gone to the OBGYN yes I have take birth control about 8 years ago and I refuse to take it again because the pills made me bleed for a whole year non stop just for them to give me depo which turned around and stopped my period fully and ate the lining in my uterus and I got sick from.

I have irregular cycles I could either stop a whole month or it starts back up every 35-42 days. My periods last from 7days up to 3 weeks once in a blue moon. This period that started on October 20th was very light and stopped on Halloween just to turn around and start spotting again. It's been non stop and we've had sex quite a few times during and after my period al the way up until last night.

Any advice would be great. We've been TTC for 2 years and we have both gone to the doctors. They say he is fully healthy and there are no issues and they have done scans and check ups on me and everything seems to be good too. So why have we not been able to get pregnant? We've changed our diets, weve tried meds, we've tried old myths of how to get pregnant and different positions. Am I just broken?!
