This may be TMI but I am curious. I went to Labor and Delivery early Tuesday morning because I was having contractions 6-7 minutes apart. They checked me, my urine was clear and I wasn't dilating more then my last check 2 weeks pier. All they told me was I dilated a 1/2. So I'm now 1 1/2 dilated as of Tuesday. But lately I've been noticing a menstrual like smell. I've never dilated before with my first and never had the show.

I'm just wondering if this is normal process of dilation?
