why in first month of pregnancy there's pain in lower abdomen n sides of abdomen also... also having too much pain at back..

A. hii...During your first trimester, you may experience cramping pain in your abdomen, which occurs as your baby develops. Cramping is experienced during the expansion of the uterus, which causes the supporting ligaments and muscles to stretch. Cramping during pregnancy is considered normal and can also occur due to other causes including gas and bloating, constipation, or sexual intercourse.. Incase pain is persistent then do consult ur gynaecologist.
