Hi, me and my boyfriend had an unprotected sex last September 24,2016. I was already delayed for a week, but then I got my menstrual period last September 29,2016. Cramps was very painful, 1day heavy menstrual the 2nd and 3rd are just light period. First week and second week of October I already feels some signs and symptoms of pregnancy like tendered sore breast, nausea, vomiting, dizziness, headache,abdominal pain, sense of smell, im always tired, I pee time to time, I already test a blood test and its negative as early as 20th of October and said it was negative. And todat October 29,2016 I am experiencing pain and bleed as well. Am I pregnant or what? Because I'm really confused right now.
