What kind of vitamins are you taking? I remember when I was pregnant with DS, my body didn't like the vitamins I was taking, and I would have the worst tummy pains - it was sooo bad... but then I changed and my belly pain went away...

Then when I was pregnant with DD I had bad tummy pains because I got gastro FIVE times during that pregnancy. I went to the doc the first time cos i was only 8 weeks and was worried about the baby - but bubs was fine - all tucked away safe and sound!!! Try not to worry too much.
