I had a lot of pain while pregnant with baby 1 and she was/is a health baby. The doctor said it is normal that some ladies have pain while pregnant, it depends how you are carrying.

You could consult a physio which specialises in pregnancy issues. I know a lady who had problems from the baby pressing on nerves. If you have been a swimmer in the past, you may be able to swim or walk around in the water in a pool. Seek advice first. I know a lady who did that for several weeks. It helped to relieve the pain.

could be the baby stretching out

I had a lot of pulling & stretching aches & pains with bub1. After being given the all clear from my doc I started a pregnancy Pilates class. The stretches & exercises helped a lot

i experienced alot of cramping and pressure pains with my second pregnancy, i was told that it was the way baby was sitting low and creating alot of strain on my lower muscles. and the pains were stretching pains.
not sure if it is what you are experiencing though
