I am 7 days late. I have taken 4 different kinds of test the past 5 days. This morning I took another one. And it was a BFN. What is the deal... My symptoms: headaches on and off. Constipation the other day. My boobs are huge! And feel so heavy! My nipples are kinda sore to touch. Blackface. Cramps. Food aversions. Last night I woke up and felt soo hot I was sweating but I was burning up! And had these terrible cramps in my lower abdomin. So I got up when to bathroom sat in the floor because I got so dizzy. I went to doctor next day to get a blood test done. He said I could get one done until 12 says after missed period.. Am I pregnant or not?
