So I tested yesterday, 12dpo according to this app. I did not use fmu.... it was negative. I just haven’t been feeling right, very sore breasts, little appetite, and at 7dpo I had a small amount of red blood and a small clot and then spotted again 10dpo, but never turned into a flow.... has anyone tested at 12dpo and get a negative but test a few days later and get a positive?
