Firstly congratulations. :D it's great news that you're having support. Cramping is normal, through pregnancy, things need to stretch and move, it can be uncomfortable. When you book in with your midwife/doctor you can then speak with them. X
As long as it's not accompanied by bleeding it's very normal to have cramping. If it's lower stomach is probably round ligament stretching. You can take a couple Tylenol and it should help. Also sometimes a warm bath helps as well loosen everything up. The other very common thing that can cause quite severe cramping is constipation. Also very common in pregnancy and very uncomfortable. :-/ hope you feel better soon tho
Yup. Very normal. Sometimes feels like PMS day after day.... Good luck!
