If your patch keeps falling off, the estrogen level in your body
could drop since you're not getting the full dose of birth control,
and you could have bleeding. Consider using the morning after pill
if you've had sex in the last five days, and contact your health
care provider about an alternative method.
In addition, if you choose to stay on the patch, get a
prescription from your health care provider for a single
"emergency" patch that you can have on hand to replace a patch that
keeps falling off.
