Is it doubling you over in pain kind of cramping?? Otherwise, it's probably normal...you have to remember you're stretching and growing for 2! So you'll have more exaggerated symptoms
Yes! Very normal! Your uterus is expanding quickly to accommodate those 2 little ones. :) congrats on your twins
Well it kind of depends on how bad the cramping pains are...
If cramping is bad then go to doc soon
