Is it normal...

To still feel tender weeks after a miscarriage? I had a miscarriage 5 weeks ago and after the miscarriage I felt tender and discomfort on one side. At my check up scan to make sure all had come away they said everything had passed but a tiny blood vessel which should get absorbed back into my body. I said I was tender and asked them if it could be because of this and they said it could be. This settled down a bit but I've just got my first AF and the discomfort has flared up a bit - it feels sore on one side (sort of between hip bone and belly button but a little lower down). Should I still be in discomfort if everything has come away ok?! Xxx
