Hello girls, 28 weeks pregnant, I noticed that in the morning when I get up and even when I lie down for a long time and then get up, it's really painful and feels like it's going into the right side of my vagina, but it goes away when I walk, and there is some swelling on the right side of my vagina, I had a vaginal hernia as a child, now I am very worried that this could be it, and I can only see a doctor next week.
