Am I pregnant?

So I recently lost my virginity in December and I've had sex a few more times unprotected.. I'm 17 and I'm getting nervous that I may be pregnant. Its been about 4 weeks and I'm having symptoms like boob tenderness, I can smell everything, I puke when I smell meat, my ankles are swelling, my temp is a bit higher than normal at about 99 and I am tired sore and nauseous I'm craving weird things and I have to pee constantly. My stomach has very small cramping not bad but noticeable and about a week after the first time I bled and it stopped. I'm concerned. Is this in my head or so I need to test.. not only that my parents will probably kick me out if I am. If I am I want to keep it.. what should I do?
