birth control
"I've been on the patch for 4 months now. The first couple of days on week one I have a low grade headache but nothing tylenol cant fix. I found putting the patch on my shoulders on my back it gets way too itchy! So I put mine under my underwear line on my outside thigh and it doesnt itch near as bad. It sticks pretty well and by the time it looks like its about to fall off its time to put on the new patch anyway. I started my patch on Sunday and when its the week without it I know exactly when I will get my period and when it will end. It lasts about 6 days (only major downside for me because without birth control mine usually only lasts 3 days.) Cramps are a little worse but bearable and only happens the day before period and day of. No weight gain."
