Need similar stories, could i be infertile?

I've been sexually active for over 10 years, I'm almost 26 years old and from philly. I get worried thinking about whether or not I can actually conceive. I've been having unprotected sex with the same man for 5 years. No scares. And dated someone else who did release himself inside me multiple times (I know it was stupid I was young) but it amazes me that I've never even really had a scare. And makes me think I might not be able to have them. My SO & I want kids very much. And I know its difficult to get knocked up anyways, its a small few day window and that's it. So someone's either looking out for me from the skies or I'm really not meant to be pregnant yet in life orrrrr I'm infertile. Which would be terrible. All these years and all these accidents just doesn't make sense. Anyone have similar stories about waiting forever to get pregnant or trying and it finally happened so I can have some damn hope to hold onto lol. I'm not trying currently.
