Go to your gp or midwife, i had this with my third pregnancy and waz diagnosed with spd (symphasis pelvic/pubic disfunction), it can get Very painful, please go get checked if you are in alot of pain, good luck x
Also please mention it to your Dr! If it gets worse please go get it checked.
Yes its normal. It is youd pelvis stretching and loosening up, so it can have room for the baby to pass This is my third pregnancy and I am 30+1. I have been dealing with this pain since around 25weeks. Just watch you activity and when you lay down put a pillow between your knees. When you get up keep your knees together...try soaking in a warm bath. Sometimes that will help to. But please make sure someone is home to help you get out of the tub if it becomes to painful. Best of luck! You are almost done. :)
