We have been having sex since the 26 of April right up until now. I have sensitive nipples and some nausea but a I am always hungry and have a lot of headaches all of a sudden. But my period is due on the 15 the May and i am having white discharge as in the picture attached. Has anyone experinced it and was pregnant?
