Ok. I am in the 3rd week of the pills and I've missed about 4 pills total. Me and the Hubbs aren't really worried about getting pregnant or not getting pregnant because we're not on the pills for that reason. The past 5 days I've had severe breast tenderness and yesterday I started having "drawing" in my breast (if you've breast-fed before then you understand what I mean, you feel like you need to nurse your baby before your boobs explode). Last night I squeezed my breast a little and bubbles of "milk" came out. My doctor says that its the normal side effects of the pill but I have NEVER experienced anything like this before due to the pill; and I can't find ANYTHING that says this is normal. Can anyone give me some insight to this, please?
