I am 8 weeks pregnant with serious constipation, i just strained really hard to get some relief. now my abdomen is in excruciating pain.

Fiber & Fruits: Constipation can be eliminated ("aliminated") by increasing the amount of fruit, vegetables, water, and whole grain also known as fiber in your diet. Straining at the stool is a good way to get hemorrhoids or a "union card in the bricklayers association."(smile)

This too should pass: NO pun intended. If you are severely constipated ,one might use a small fleets enema or glycerin suppository. This is just to get you going. I would ask your doctor if you can use miralax (polyethylene glycol) daily as a stool softner to make it easier for you to go. NO the pain should only be temporary. if persists see your gyn.
