Is it time to give up?

I suffered 2 miscarriages when I was very young and very stupid in a previous relationship (I was 15&16). I have been with my current boyfriend for 4 years and we have been trying without actually saying we are trying for maybe a year. We dont use protection and I’m not on any form of contraception but every month AF arrives. I have a very normal period, it is never late and always lasts exactly 4 days.

My SO always jokes about maybe having slow swimmers! I’m now starting to think this isn’t a joke and maybe we can’t conceive together. I’m only 23 and he is 25 so we are still very young and have loads of time, but when you want something so bad and it just doesn’t happen it is absolutely heartbreaking.

Am I reading to much into it? I feel like I’m putting too much pressure on myself.
