The period is 22 weeks. I stand/walk/sit and sometimes lie in one position, then my vagina hurts where these bones and my chest hurt. Discrepancy? Not too early? And at 18 years old I had a fracture of the coccyx, pains appear when sitting for a long time or lying on my back on a hard surface (even before pregnancy), does it affect natural childbirth? From the doctor then heard something but didn't delve into details. In the maternity ward they never asked about injuries.
