33 weeks pregnant woke up with lots of clear and snot like discharge, waited an hour and changed pad to see if it was continuous. When I changed my pad I've noticed the color of the discharge changed from clear and snot like to watery and sticky and yellow. From what I can tell there's no foul smell, I've been having cramps in my stomach since yesterday laying down helps but I can nearly all the time feel the discharge leaking from my vagina. I am worried and can't phone a doc because my phone speaker is broke.
