Hi dear , I have gone through your question and i understand your concern.Ortho Evra is a contraceptive skin patch containing a combination of female hormones (ethinyl estradiol and norelgestromin) that prevent ovulation (the release of an egg from an ovary). So firstly your cycles are anovulatory- no ova, no fertilization and no pregnancy. secondly as per your details as you removed patch,hence it lead to withdrawal bleeding. thought the flow is heavy with clots but you must not worry because this is not pregnancy and this is due to hormonal fluctuations as you removed patch. you may take iron folic acid supplements if feel so much lethargic and pale looking . and take plenty of water and green veges. advice:- If an Ortho Evra patch is partially or completed detached for less than 1 day (up to 24 hours), reapply it to the same place or replace it with a new patch immediately. No backup contraception is needed. If this event occurs for more than 1 day (24 hours or more), or if the woman is not sure how long the patch has been detached, she should stop the current contraceptive cycle and start a new cycle immediately by applying a new patch. Backup contraception, such as condoms, spermicide, or diaphragm, must be used for the first week of the new cycle. don t worry you will get well soon with reapplying patch and starting new cycle.
