Hi,Amy.
Glad to hear you and Evie are doing well.
Sorry to hear your still having the pains.Although after pains are worse the more children you have,I don't think mine have ever gone on as long as that,so I would get it checked.It may be just your body healing,as you've had four close together,that's a lot of months pregnant in a short space of time.It'd be worth checking just to make sure it's all going back together correctly.
Better to be told it's nothing to worry about.Hope you feel better soon.
Can't believe 7 weeks has passed already!
