Hi everyone☺️ , so since Tuesday I've been having this weird discharge. I had just finished intercourse with my husband and I went to pee and everything and when I got up this discharge came out it was kinda yellowish with white and clear and really sticky and it's never happened before after having intercourse. Well that happened Tuesday , now it's Thursday and I keep having that kind of discharge little by little , yesterday Wednesday I had that kind of discharge and today Thursday in the morning it wet my underwear and that discharge was everywhere xc what could it be ? I'm a first time mom and everything worries me haha
