I have been on the patch 6 months and the first month I did the whole 3 weeks on and one week off but I didn't want to get my period. I didn't want to get my period because I enjoyed not getting it on my last birthcontrol control which was mirena. So I had a really bad headache one night and I couldn't sleep so I took it off for only 8 hours. It helped alot didn't have a headache nomore but ever since I took it off and out it back on I always keep it on and never take a week off. So why have I kept spotting since and got my period for a week then after a week I got it again. I took it off since I'm bleeding to the my body do its thing and then when I'm down bleeding I will put it back on.. But why question is why do I keep bleeding while still on it ..
