Can you get tested for fertility?

I’m just curious or is it kinda like a guessing game? Like you need to actually be actively trying to conceive in order to figure out if you’re fertile?

I guess I’m just worried because I’ve been having unprotected sex with my husband coming up on 6 years now. He always pulls out and I’m not on any kind of birth control. It’s not like we’re trying but we have had the kids conversation and if it did happen-it would be a blessing for sure. We have a house and full time jobs and cars.. etc...

a lot of people tell me to not worry until we start trying. A lot of people also tell me it’s crazy I haven’t gotten pregnant. My cousin accidentally got his girl pregnant and they were only together for like a month or two.. I know a couple stories like that.

It just makes me feel infertile or that my husband might be. My periods are always spot on, but they are pretty painful. Always have clots the first day or two. I always wondered if that alone could be signs of infertility. I just don’t wanna stress so any insight helps.
