What do I do?!

I’ve been with my current boyfriend for 9 months, we started sleeping together pretty much straight away but was using protection at first. But when we got serious and we both were checked out we stopped using protection. I have a period every month as normal, but I do get extremely bad cramps on the first day. Anyway, my query is, should I be checked for fertility issues as I have never (even with past partners) had a pregnancy scare? I don’t want to end up pregnant just yet, but it would be nice to know before I plan on wanting them and then possibly finding out something bad?
