Re: are sore breasts a sign of being pregnant?
Well, I don't know if this is the answer you want or not, but yes. When I was in the first few weeks of my pregnancy it hurt to drive because my arms would brush against my nipples and cause pain. That was one of my first clues that something was going on. My breasts had never hurt before during my monthly cycle, though, so it was something new for me.
Has her pill prescription changed? If so, it could just be that the hormone levels in the new prescription are different enough to cause pain.
Hope this helps!
