I had my 30 week check up but all my doctor did was check the baby heartbeat and measurements of my stomach. I have to wear pantie liner bc I sometimes have little bit of discharge and today I noticed a very light brownish blood on it and when I wiped I had more? Should I be worried bc it all started today, and when I pee i have this strong pain feels like a cut that hurts badly so I was thinking maybe that could be it but I know I didn’t cut myself down there?
