Hello Everyone!

I started having sex with my boyfriend 8-9 months ago, we were both virgins when it came to intercourse. He’s always finished/cummed in me and I’ve never gotten pregnant from it. We are both almost 20 and are not ready to become parents, but we are shocked as to why I haven't gotten pregnant yet. As I was always taught that if a man cums in a woman, she most likely will become preg, I would love to have babies in the future thus is why this was a bit worrying to us at first. I’ve always had irregular periods, there has been times when I could have sworn I was pregnant, because of all the symptoms, but then my period showed up. Last time, I thought I was pregnant, I did not get my period for 1 or 2 months, I was however, spotting a lot. Until the very last days of the month, my period finally came. I had cramps and that sort of stuff before, but no period. Anyway, I just want to know if this is normal. Has anyone been through the same thing? If so, how long did it last and when did you end up getting pregnant? Please share your experiences. As you can see, I am not educated on this particular topic. Also, how can I find out when I ovulate???

Thanks!!!
