Hi. I've been on birth control for 7 months, had my last period on the last week of October and skipped my next pack for November. I've had unprotected sex multiple times since. And I have missed my period now by 8 days. I've been feeling bloated nauseous, light cramping in my sides, and I feel I'm hot temperature wise on and off but I took two urine tests, one on the 6th late day at night, and another in the morning on the eighth late day-- both were negative. Could I still be pregnant?? If not, what could it be???
