What should we do about my girlfriend's spotting while on the pill?!

What should we do about my girlfriend's spotting while on the pill?

She's been on the pill for 9 months (give or take) and she's been having breakthrough bleeding. She was switched to a generic brand a few months ago by the University clinic; it's diminished her sex drive and this month, halfway through her pills, she's had spotting and also said she's been dizzy. It started on Saturday. Could this mean she's pregnant? What should we do about this? We can't really contact the University clinic since it's far away. Where else could we go?

She takes it very regularly. She missed it once, but that was last month, not this one. We don't use other forms of birth control with the pill.

I really want to know whether this indicates pregnancy for sure, or if this is an adverse reaction to the hormones. However, since she's been on it for so long, I assume she's used to it. Would this make the pill ineffective? Is the spotting a sign of that?

I already asked this elsewhere but I noticed all the similar questions were under women's health.

frank,
don't freak out. it is normal for a girl to start spotting if she switches the kinds of pills she takes. it does not mean pregnancy. it's good that she takes it regularly. the thing they never tell you is when you switch there's possible spotting for days even weeks. as long is it not heavy bleeding you're good. if you have any other questions let me know.
