So I am 26 weeks 4 days and this is the second time I have had a rush of completely clear warm water like fluid with mild cramping. I'm 100% positive it's not urine, it does not smell like urine and I can not control (like I would when I pee) Wednesday I got sent to the birth center for it they said I was ok and it was not the amniotic fluid which is good.But it happened again today and my Dr wants me to go back again to the hospital. It's very frustrating has anyone had this before?
