I went straight home. They also advised me to get in paracetamol and ibuprofen and supplied me with dihydrocodine with instructions to keep my painkillers topped up and to take the dhyhydrocodine if I felt any pain in between.
After an hour I started cramping. I just set up camp in bed and went to the loo every so often. I think I felt it pass quite quickly, maybe 45 minutes after the cramping. It was a strange feeling. I didn't check the toilet, you don't have to. You just kind of know. I was cramping for the rest of that day, from about 11am to 6pm and you do bleed heavily. I only had to take one dose of extra pain relief. It was like a heavy sore period. Not pleasant but manageable.
The next day I was up and about, taking paracetamol if needed but still taking it easy.
I'm a week after now. Still bleeding but it is trailing off. Not in pain.
