Soreness when having sex trying to conceive?

Has anyone else ever experienced soreness when having sex after ovulation? I'm in my tww and a few days ago I was very sore after sex and then today I was a bit sore during. I know this is a bit tmi but I was curious if this might have anything to do with possibly being pregnant. We are trying to conceive and I'm hopeful. This is my first so I have no idea what to look for besides the general fatigue, morning sickness, etc. I've never really been sore before in our past, so what could it be? Thanks!
