Sorry for long post.. need advice..

I had an epidural and then Had complications in birth, my body filled up with my own fluid at least 3 of the bed pan pots. They tried to break my waters but didnt have much fluid and they didnt realise so was still poking around in me hard trying to break it. So I had an emergency c section 5 weeks ago due to other circumstances. I was bleeding for just under 4 of those weeks and then had yellow mucus discharge for a few days then experienced what I thought could be my period for 4 days which has now stopped. Stupidly enough me and my partner had intercourse around 4 weeks as the bleeding stopped But for about a week I've been getting cramps in my left lower stomach and back that seem to be intensifying. They feel like someone has there hand in squeezing what ever is there and it's getting uncomfortable to walk. Nothing is helping it I've tried a hot water bottle, tablets, resting, hot showers... anyone else experienced this pain and could help me?
