So I'm on ortho tryclin-lo for PCOS and about 2.5 weeks ago, after I started a new pack (I'm on for three months straight, off one week, start again) in the middle of the three months cycle and I started to spot. I wasn't really worried; as you know, hormones build up over three weeks with ortho and going straight from the highest amount of hormones to the lowest, I expected some spotting. Well, it hasn't stopped. For the past 2.5 weeks, I've had major spotting. It's all old blood (thick, very brown in color, almost no red blood) and sometimes I get cramps. I take my BC everyday at the same time and it's still spotting. I'm in the middle of the pack (I start the highest active pills on sunday). Help?
