Question: Several time I had a back pain what to do or which exercise I should do
Answer: Hello, I'm happy to help.
During pregnancy, your body makes a hormone called relaxin that allows ligaments in the pelvic area to relax and the joints to become looser in preparation for the birth process. The same hormone can cause ligaments that support the spine to loosen, leading to instability and pain.
Here are a few tips that might relieve you from back pain :
Ice or heat packs.
Sleep on your left side, and use a support pillow under your knees.
If these dosent help, please consult your gynecologist for further treatment.
