Should I be concern ?

Li

In about to be 24, I’ve been with 5 man in my entire life. My first time I was very young so we just had sex like 3 times, all with the pull out game. Second was a one time thing with a “friend” did it work so we just kept being friends, also pull out. 3rd time this was my firs boyfriend for a year, for the first months I was taking any contraceptives but I used to duch ( put water inside and clean the sperm) after that I took contraceptives. 4th also one time thing and took plan B. Last is my today boyfriend. Been with him 6 years and for the first 5 I took contraceptives and now it’s been a year with out taking anything and having unprotected sex and I’m not getting pregnant. I’ve never been pregnant. Is this not normal or I just had a lot of good luck? I’m worried because I want to be a mom already. I do OPK and they come back positive, I had test done for my hormones and they are good too. Even ultrasounds and everything is fine as well. What’s going on?
