Has it just been a min since I got dick or??

I am in a long distance relationship an we haven’t seen each other for about 3 weeks, and (obviously) we got it in but it hurt like in the middle of my vagina like a sore feeling. A month before this I had vaginitis and a UTI and it felt like that. Is it just me being too tight cause it’s been a sec, my vag is messed up, or iud thing maybe?? (ive had the Skyla for a year and a half and I’m wondering about it)
