Girls, can you please help me? I'm at 38 weeks pregnant and the discharge is getting annoying. They look like phlegm but they don't wash off. At 35 weeks, my gynecologist said to rinse vaginally with chamomile diluted with water and candles Terzhinan and said that I have a soft cervix. Now I read and think it might be a plug coming out, but is it normal for the discharge to be so frequent every day, 4-5 times? Is it normal for the plug to take this long to come out?
