Sore boobs.. could it just be Beyaz?

So, I've been on Beyaz for about 4 months now... And I've had sore boobs while taking this before... But man, are they getting more sore.. Can anyone else who is taking Beyaz tell me how they do on it? I'm starting to get worried something else is going on. I've been pregnant before and it feels alot like the symptoms I had then... But I can't tell since I know Beyaz is common for having pregnancy like symptoms. :(
