Hey there! Let me ease your fears! I know it's near impossible to not worry, but I was in your exact shoes. I was completely convinced we would never be able to have kids. Firstly, my OH is underweight, smokes cigarettes, and has been a regular weed smoker since he was 11. We have never used condoms and for the first 3+ years of our relationship we used the pull out method, with never any pregnancy! Then we decided to ttc, so for two months we had sex multiple times around the time I thought I ovulated, and nothing! On top of that, my boyfriend has clear semen, never white, and doesn't produce a ton, so I was convinced he was infertile and maybe even I was (my periods were getting more irregular). Then I decided we should quit trying. We never went back to the pull out method but we weren't actively trying either. Then 8-9 months went by, and lo and behold, I had a spare test, and I figured I'd test and it was positive! I was completely shocked, as I just believed I wouldn't get pregnant. After all, we'd been using pull out for so long with no accidents, and then took almost another year without any prevention before I fell pregnant. I am now 9 weeks and have seen baby on the ultrasound, so I know it is real. So the moral of my story is, NEVER make yourself believe you wont be able to get pregnant, even with your bf's situation, and even if you feel like you should be pregnant already. I thought with my age and the high rates of conceiving, that after around 4 months of regular sex the odds were high that I should have been pregnant already, but it took months more before it actually happened. Ohh, and if it helps at all, you can look back at my posts in ttc from December of last year from when I tried for a couple months before giving up. In one of them I brought up my bf's semen, I was very worried I'd never be able to get pregnant!
