Over the last two weeks I have been experiencing these things. Thirst, more appetite, frequent urination, constipation, increase in vaginal discharge, night sweats accompanied with chills off and on and increased fatigue. Could this mean I am possibly pregnant? Had un-protected sex on the 11th and 13th. Period is due on the 1st. I know most say to wait for your period but things in the body just seem different. Advice would be very appreciated. = )
