I believe I may be pregnant. My boyfriend and I had unprotected sex and about a week ago I began feeling hot flashes, nausea, fatigue, dizziness, lightheaded, sentitive breasts, and the occasional back pain. However, I felt cramps like I had my period. No period. They weren't usual cramps. They were different. Everything I ate, the smell made me gag. Now I'm 9 days late on my period and I began to bleed. It's very light though. Is it still possible that I'm pregnant? Please help! My cycle length is normally 28 and I'm on day 34.
