Okay well I had sex with my boyfriend about a week and a half ago, I was on my period & my period usually lasts 3 to 4 days, I had sex with him on the 2nd day of my period. After the 4th day of my period it started turning a brownish color & I got very worried. That lasted for 2 more days which I have never had a period to last 6 days. I really didn't pay attention to it until about 5 days after we had sex and I found it really hard to sleep at night, I felt nauseous and I couldn't sleep on my stomach, I also started feeling really hungry. Everytime I stood up I felt really dizzy. I thought to myself it was way to early to have pregnancy symptoms even if I was. So I looked it up and everything that was happening said it was a pregnancy symptom, it has now been a week and a half since, and I am now starting to experience back pain, and a white discharge coming from me. Sleepless nights are still happening, so I would really like to know am I pregnant, are these signs that I am, and how soon can I take a pregnancy test for the most accurate results?
