Sex after birth with episiotomy ?

I’m just 6 weeks postpartum I had a small episiotomy cut and we had sex but I’ve again started bleeding again after an 8 day period just ended and it wasn’t the most comfortable to have sex mildly painful and now I have the most intense painful cramps is this to be expected has this happened to anyone else. I was so looking forward to getting this back and I feel so let down.
