So me and husband had unprotected sex a couple days before my period. I missed my period.. I am on Day 5 with no period. My period is always on schedule. I took a test which was negative because it's too early. My boobs are so sore. I have extreme back pain. Also I have a white yellowish discharge. My stomach area (not cramping) has been hurting off and on for the past week. What do I do? Just be patience.
