Pain during sex..

Okay so I’m exactly 15 weeks pregnant with my first and we have sex about once or twice a week now and NORMALLY I’m in no pain afterwards just tired of course. But today we did it everything was as usual (he wasn’t rough he didn’t go too deep and we foreplayed first so I was super ready) but after when I went to clean myself up it kinda stung/burnt and it isn’t like to the touch, it’s a lingering pain.. is this a normal thing? Has anyone else had this? It seems to kinda be easing the more I relax but its discomforting still... help😢
