Hello, based on your description, it is considered that the pubic symphysis is separated. Due to the influence of endocrine factors, the symphysis pubic ligament is relaxed and the weight of the fetus compresses the pelvis, causing the pubic symphysis to be separated. In the third trimester of pregnancy, you should lie on your left side to reduce standing and relieve the symptoms of pubic symphysis separation. After delivery, the pubic symphysis separation can quickly return to normal.

I hope my answer will be helpful to you, and I wish you and your baby good health!
