I still haven't started, FF says I am 21 dpo but I think I am more like 19-20dpo. I woke up today with really sore breasts this morning and it has only gotten worse. I bought a box of FRER tests tonight and I am going to test in the morning. I have no clue what is going on. It hurts so bad when my dd nurses I am nearly in tears. I guess this means that I am either going to be starting soon or that I am pregnant. I don't know and it is driving me crazy!
