yeast infection + period?

[xx-socold-xx.livejournal.com]

I've been quite itchy lately. Most of the time its external, not actually inside the vagina. However, there will be times when the actual vagina itches. I have been having pretty normal discharge until yesterday, when I noticed it was kind of in small clumps, which is something I don't usually get.

This morning, I felt like I was having stomach problems so I went to the bathroom. The more I sat there, the more I felt like they were period cramps instead, but I'm not supposed to start for another 4 days. But hey, that's not too far off. So, when I got up and wiped, I had the same clumpy, small discharge but some of it was tinged pink. Could that be my period starting, and just mixing with this clumpy discharge? I do have some cramps, so I'm inclined to believe its not any sort of serious matter, but I don't think I've ever had this happen before so id like to check. :/

I've also been on antibiotics (ceftin) for about. 5 days now.
