u cant avoid a miscarriage other then not to lift crazy heavy things. and being careful not to fall and etc. But anywho. congrats. the risk usually stops at 12 weeks, or thats when i thought it would be fine to think different even though some women do miscarry farther along then that. But dont stress over the small stuff jsut enjoy your pregnancy. 1st pregnancy is a new wonderful grand experience
Technically you are at risk your entire pregnancy, however the highest risk is in the first and early second trimester.
Miscarriage is for the most part unavoidable, it's due to genetic issues with the child.
Typically your first tri-mester is ur highest possibility. However, it can happen into the 2nd but its very rare.
