I was told my bleeding should get less and less each day, but recently it's got heavy again.. Really heavy. And I have stomach cramps, it's horrible

to make things worse, I also have a headache, and while i'm looking after .Jenny by myself it's pretty tough to stay patient with her. She keeps wanting to sleep on me rather than in her cot, and she cries til I put her onto my chest. I don't want her to make a habit of it, but right now it's better than her crying making my headache worse.
The pains are so bad they're reminiscent of being in labour! Should I call my health visitor/midwife?
Argh this is horrible
