38 weeks 6 days pregnant. Scheduled c section is on the 5th. Tonight I have been experiencing really sharp stabbing pain in my vagina (feels like someone is using a knife and scraping it out) plus an increase in pressure in my bottom. The pain is constant and doesnt go away. I have had a few braxton hicks this evening they are getting somewhat uncomfortable. But nothing compared to the constant pain in both areas. Anyone know what this could be? Was checked at 37 weeks and was still high and closed
