Today during intercourse I noticed I was leaking a lot of a thick white not climbing discharge/mucus. It had no odor but made a huge mess! There is no itching no burning and no odor. I ve always been eating very little the past few days due to that fact even thinking of food makes me nauseous. Ive yet to be sick just have the feeling. I ve also had excessive lower back pain, an almost period like cramping pain. I ve had a bv, uti, yeast infection and it is nothing like any of those. What could it be!?
