Sex while pregnant

Breein

Sex feels great until it doesn’t, in the middle of sex it all of a sudden feels like he hits a sensitive spot at the very back. Of course he always stops when it hurts. About a month ago, I got put on pelvic rest for a month because of a subchorionic hematoma . Since my check up was yesterday and the Spot is gone, we just tried again and after maybe 10 min I get the pain again. Has anyone else experienced this? And/or know what it’s from?
