Wondering if anyone may know the cause of tender breasts that have lasted 3 weeks? It is 88 days since the first day of my last period. I have taken 3 pregnancy tests BFN,possible evap line, and a BFN digi. My breasts will hurt a week before I get my period but they still hurt continuously. They aren't so much sore to touch just when there is even a little bit of pressure on them. I know this is a broad question, just curious if anyone has had sore breasts last this long.
