My periods have always been short and light - 3-4 days and maybe it'll be regular one day... however since I have been taking birth control pills, weird things happen. I first started using them in april of 2007 and they were Ortho-Novum 7/7/7. About this time last year, I was lactating. I had never been pregnant and I wasn't pregnant at the time, but my lactate was like 23. The doctor changed my birth control to Yaz in February earlier this year, but now during the days when I'm supposed to have my period, I don't. About 2 days later, I have brown spotting. This last time I had to douche to get it all out. And it doesn't smell. Eventually it will all come out, but I end up ruining underwear. The fact that my periods aren't like clockwork doesn't help either. I'll have my period on the inactive pill one month, be a week late the next, be half a week early after that, and then i might not have my period for 1 1/2 to 2 pill cycles... Anyone have any idea what's going on with me?
