Difficulty getting pregnant now?

Amanda • Boy mom 💙💙💙 due July 1st with 4th.

I have 3 boys: 5,3, and 1. We didn’t try for the first two (pull out method). The 3rd one we had sex a few times where he didn’t pull out. I just decided to take a test to see if I was pregnant since I feel I get pregnant easily. I don’t think I had missed a period (I’m irregular and wasn’t tracking it) and I didn’t have symptoms yet. Sure enough there was a faint line.

Anyway.. I guess my question is now that I’m 35, is it going to be harder for me to get pregnant?
