To much caffeine?

I've noticed I've been taking a little bit more caffeine in recently. I have a cup of small coffee every morning. And maybe drink 2 sodas a day. My boobs on my sides have been killing me, idk If that's one of the reasons, but I'm also due for AF little over a week. Question is, can caffeine make your breast be little more sensitive than what they normally are??! Husband and I didn't track at all this month no opks, no temping, didn't even note when we DTD. I doubt I'm preg. Anyone?!
