... swings, I've noticed one of my breasts have been tingling for the past 2 weeks. I also forgot to take two pills in a row in at the beginning week 3 but took them as soon as I remembered (the breast tingling started before I forgot the pills). I had a few days later and today I noticed that the veins in my breast are more visible than before. I've also had some very light spotting throughout this month. Prior to this month, I had take all the pills pretty much on time. Should these symptoms cause me to worry about pregnancy?
