birth control
"The first pack my doctor wanted me to stop after the first month to try to see what effect the medicine would have with my period and to only continue if there was no abnormalities. I followed her instructions and toward the last 2 weeks of the 3rd set, I started seeing some "color" that led to spotting. And my period took a while to start during the yellow pills, but was short and light.  Now that I am on the 2nd pack toward the end, just about a week ago, I started spotting again. But this time it's heavier/more constant. Rarely worth a pantyliner or anything at all, just really annoying because I don't know if it will get heavier at any moment, stop, or stick around until the "real" period comes. And will it get worse for the next pack?"
