"i have been on the xulane patch for 3 months now. during the first month, i did experience some pregnancy side effects (am nausea, food/smell sensitivity, painful breasts) especially on my patch change day. i believe it is normal as your body is getting used to the amount of hormones you are receiving. when it came time for my 4th week (off week) i did have a severe migraine that lasted up until i began my period, 2-3 days after removing the patch. it was so debilitating that i did consider discontinuing the patch. however, things returned to normal with my period and i did notice a lighter period that lasted only 3 days."
