Hi
Sorry to hear your sad news.
Your in the right place to get help and support through the bad days.
I agree with flower child its a bad idea to swim or bath or get into a spa as you could get an infection and that will cause lots of pain and could damage the lining of the uterus. I don't want to scare you or anything but its best to be informed of what could happen.

Everybody is different and it depends on if you had a D&C or natural miscarrage as to how long you could bleed afterwards.

Cheers
Chris
