I have two embarrassing questions to ask but I must know from other ladies that have experienced it. I'm 20 weeks and 5 days pregnant, I haven't had sex with my bf in the past two weeks I want to badly but I can't get wet and it's so od I hate it and I'm not sure what to do I've tried it all. Has this happened to any of you ladies while pregnant?. The other question is increase in discharge it's so annoying it happenes throughout the day feels like I peed on my self while I'm walking or sitting down it doesn't smell or itch it's not thick. it's slimey  comes out kind of watery but after it dries up it turns white. Has this happened before i find it disgusting makes me feel funny I just feel like sitting on a toilet or in my tub all day. Any advice????.
