Ortho Evra patch contains two hormones: norelgestromin and ethynil estradiol. When the patch is applied the hormones are released through the skin, and decrease the production of certain pituitary gland’s hormones, thus preventing ovulation. It is applied on the skin for three weeks, and removed the fourth.


One of the side effects of the Ortho Evra patch is breakthrough bleeding or spotting. It might vary from light bleeding between periods to breakthrough bleeding which might be similar to your regular period. In a very few women (0.1% in clinical trials) a missing period might occur. It might be related to pregnancy if the patch was ineffective, but might be the only side effect as well. The hormonal imbalance might have been additionally aggravated by the use of the plan B pill.


If you miss for two periods in a row, then you might want to visit your gynecologist and have a hormonal laboratory test to check if you have a hormonal imbalance.
