No pregnancy

So me and my partner have been together a year. We used the pull out method for 3 months but after that he started Cumming in me. This means he's been cumming in me for 9 months and I'm not pregnant. I also heard that the pull out method is unreliable. He also didn't pull out all the time anyways.

So I've been getting cum in my vagina for a year and I'm not pregnant... Could this mean I have fertility problems??

My period has always came on cycle day 30 and lasted 6 heavy days. Last month it came on cycle day 43 and was extremely light and lasted 3days. (I took a negative pregnancy test 3 days before it came)

This month I'm on cycle day 33 and no sign of period.

Should I go to the doctors? Is something wrong? I don't know what to do
