I was having brownish discharge with some pink/red to it for a couple days so I went to the ER yesterday and we found out the baby, that should have been 9 weeks, was measuring at 6 weeks. So I went back today and was told in the last month my levels have only doubled and I was in fact going to have a miscarriage. The gynaecologist suggested I take pills to make the miscarriage happen instead of waiting for it to happen naturally,which could take a while, so I’ll be inserting the pills vaginally tonight and tomorrow night. Has anyone else had to do this? Any major side effects besides the cramping and bleeding?
