So frustrated!

I was so sure I was pregnant this month! I have had the most painful breasts I have ever had, at one point I was even wearing a sports bra to work because any movement was making me wince in pain. Then four days ago these bright blue veins appeared, starting up on my chest and running around my areola and towards my nipple. I've never seen these, I could actually trace them all they were so dark. Then I got the runny nose, I was positive when I tested I would have my bfp, so many strange things were happening to me. But there it was, bfn and AF showed up the next day. Even stranger, I only had cramping on day 1, and I usually have it all 3 days, and my breasts are still sore, although less so, and the veins are still there. My body is going crazy on me, and its making tracking symptoms so difficult.
