Past 2 weeks have had INTENSE pressure in my bottom back and in buttocks. Past week lighting pains in vagina especially when I stand I know this is because baby's head is down as per ultrasound and midwife. I've had upset stomach for about a week and been sick 3 times over past few days. Feel so tired as well. I had midwife today she said everything looks fine etc had anyone had these symptoms around this time? I'm 37 weeks Friday.
