Af is 4 weeks late, after weeks 1 and 3 I took a test and got a bfn. For the first 3 weeks I had sore breasts, constant fatigue, and I was more emotional than normal. My husband and I were intimate both days before, the day of, and both days after I think I ovulated in February. I don't know if I should get a blood test done or keep waiting.... Any advice would be more than welcome.
