it depends on how small you were before you got pregnant. this is my first baby and im a little over 8 months and im still uncomfortable. It gets a little easier bout month 5 becomes less painful and not so much morning sickness. good luck
If you are in the early stages of pregnancy and have not started wearing maternity pants then you can try wearing them. They were much more comfortable for me and the cramping slowed down. I am now 4 months and for the most part they are gone. With my 2nd pregnancy they started back up about 8 months.
Try warm baths and try to relax it will help the cramps. Good luck!
