I had sex about a week ago, and unprotected... Two days after sex I started feeling dizzy when I would only wake up but then later on the week I would start feeling dizzy throughout the day and then start feeling nauseous because the dizziness was so bad. I haven't had my period yet and I don't even know if its coming since I had two periods last month. I was recently on implanom birth control so wondering if this could be why I haven't had my period yet? I have been feeling dizzy still and my stomach feels weak and now beginning to feel tight and bloated and sore. My boobs don't hurt and I'm not throwing up but could there be a chance that I'm pregnant? By the way the guy didnt cum in me either, he came in my hand all three times ...
