My boyfriend and I are actively trying. My last period was feb11. I am about a month late, I have been feeling nauseous, bloated, constipation, sore breast, lower back pain, headaches, a little heart burn, I took 4 pregnancy test, their negative, went to the doctor, I told the doc about what's happening, so I am being tested for polysistic ovarian and to check the hcg level, my question is I had sex last night and I woke up with bright red blood.. usually I would feel cramps with my bleeding, but I feel nothing.the bleeding has stop. What does this mean?
