How many of you have had, um, interesting? bowel movements since being pregnant?

Last week, I couldn't poop. This week, I can't stop pooping (bad diarrhea ). Is this normal?

I had Fibogel on Thursday night to help it along, all good Friday & Saturday. Sunday... one bit into lunch and had to run to bathroom. It hasn't stopped I haven't eaten anything that would usually cause this (dairy products, I'm lactose intolerant), and I don't feel unwell. I don't get it.
