So my AF is due tomorrow. My breasts for the last week have been very sore and sensitive and fuller. Before my AF came last month I was TTC and noticed my breasts were sore but mainly just the sides. This time it's the sides, my nipples, and my inner breasts as well. Also, I just noticed today dark blue veins on both breasts. I don't know if I've gotten this before and just not noticed or if this is new for me. Does it sound like I could be pregnant? I'm 13 dpo.
