Normal?

I don't have normal bowels In the first place but I'm 5 weeks and I've been taking my parental pills and I've never been SO constipated. I called my ob nurse yesterday and she said  to take a stool softener. I've taken two and IM SO CRAMPY, more than usual. I've been cramping no blood just cramping. I know cramping is normal but is it from the stool softeners why I'm so CRAMPY now ?
