Pain during sex?

I’m a stay at home so it’s kind of hard for me to go to the doctor.

I was just wondering if any other women have had this problem. So I missed my period for a month and I had no idea when I was going to get it again, I was like 6 weeks late. My SO and I decided to have sex on the 24th and it was painful it felt like everything was burning down there, and right after my period started. Then we decided to have sex again today because I stopped bleeding two days ago and I still had the burning sensation. I’m just curious because this has never happened to me, has anyone else had this happen to them?
