Please tell me, is it normal for the 27th week of pregnancy to cause pain in the vaginal area when walking, when getting out of bed or turning over on your side? It hurts when I stand up from a chair and every movement causes pain. The midwife said that it's normal as long as you stretch your pelvic floor. It started at 20 weeks but has been increasing lately. Has anyone experienced this? What could be causing it?
