Hi, just recently I noticed that i started to get big blue veins on my breasts. On one, it goes down to the nipple and the other it goes down and surrounds the nipple. I have also had sore breasts at random times this month, mostly in the morning, then it goes away. I have been on the pill for 4 months. The first month I had no problems except for some unscheduled bleeding for a few days. The second month, i had to go on an antibiotic which made my period more heavy than the first month. The third month, my period was again more heavy than the first. This month, I had unscheduled bleeding but I could tell it was from the birth control, not pregnancy because it lasted a few days. My period is only a day late but I was wondering if you think I could be pregnant or if I shouldn't worry yet?
