I'm almost 35 weeks pregnant with dc2. Have been experiencing really sharp scratchy pains in the vagina (I say vagina as I presume this to be the bit where the penis inserts/tampons inserts/baby emerges). It is right at the top (to the extent that I wouldn't be able to examine myself due to my bump in the way). It is really sharp and literally makes me clench my thighs together until it dies down. Have read online that it could the pressure of the baby's head (it is now engaged)...but I didn't have this with my son (18 months old). Any idea what the bloody hell is going on down there?
