Vagina Problems *Graphic Description*

I noticed last time me and my partner had sex it was a little painful (we stopped the sex because I didn't want to continue). Well we tried to have sex again and he couldn't even put a finger in without me being in pain, so I got him to take a photo of my vagina so I could see if there was an issue (he was clueless). In the photo it almost looked like I'd torn my vagina, or at least the skin at the opening of my vagina (not the labia, it was further inside than that). When I asked him about it he said it was sort of loose and when he prodded the loose bit of skin it was really sore/painful.

I had an episiotomy with my son 2 years ago and had a D&C due to a MMC last August but this is a very recent issue, I'm also currently pregnant. I don't know if I should try to make a doctors appointment, my GP is still mostly closed during the pandemic. Do I mention it to my midwife instead? I've never had a vagina problem before and honestly I'm clueless.

No weird vaginal discharge or smell, no rash or anything either. Just pain specifically in the place where I have what appears to be a loose bit of skin.

Any ideas or guidance to what it is/what I should do?

Thank you!
