I didnt have the problem that early, more like 4 months for me.. and ohhhh my it was awful!! Ask your Dr for something. Mine gave me a liquid drink via proscription.
When I was pregnant it was horrible but my doc told me prune juice mixed with milk of magnesia. She warned me it would taste terrible but it works for constipation
Try the orange flavored Metamucil. It keeps me regular & with ease. The Mira lax & co Kacey made me more constipated.
Also eat papaya every day helps a lot.
I am wondering if the miralax is making me worse. I actually ended up having to have an enema last night :( I've just been miserable. I'm going to see about the Metamucil
Take colace, it's a stool softener and safe for pregnant women...that along with a small amount of prune juice...don't over do the prune juice though, it'll cause gas and upset tummy...i usually go with maybe 4oz. that does the trick for me.
