can heavy lifting cause a miscarriage?

Danielle • I have a 6 year old son and am pregnant with baby number 3! I had a miscarriage and am now 36 weeks!
I am 10 weeks and today my 6 year old son had to have dental work done. He wasn't all the way sedated but he was not able to walk so I had to carry him to my car and into the house after it was done. He weights 51 pounds. Now that I'm at home resting with him my stomach is kind of hurting not sever but it has be worried. Thanks for any advice.
