Discomfort during sex?

I recently broke my virginity (I'm 20 years old), and I've been slowly but surely getting the hang of sex 😂. It hasn't been particularly painful aside from some initial awkward discomfort the first time around. However today when my boyfriend thrusted I got this really uncomfortable feeling in my ovary area that hurt. We changed positions and he went a bit slower and it was better after that, but I wanted to know if anyone else has experienced this and if he maybe thrusted too deep or if it's something I should be worried about? (Sorry if this is a dumb question, I'm obviously inexperienced and don't really have anyone to speak to about it)
