How flush or taught should ortho evera patch be on the skin?

recently started using patches.. i don't tink that they have become partially detached but i have noticed very slight raising around edges and sum small air bubbles underneath patch? does this constitute partial detachment and should i change the patch? Will it still be effective?How flush or taught should ortho evera patch be on the skin?
well i searched a little and mostly found that this patch causes blood clots. I did find this in a blog tho:





What if my Patch falls off?


If partial or complete detachment has occurred for less than 24 hours, you should try to re-attach the Ortho Evra patch. DO NOT try to use any kind of tape or alternate adhesive! If you have difficulty re-attaching, apply a new patch in the same place. Keep your patch changing schedule the same as you had it before. In this case there is no need for a backup contraceptive.





If partial or complete detachment has occurred for more than 24 hours or you are unsure as to how long detachment has been, you may not be protected from pregnancy. You should remove the old patch and apply a new one. Your Ortho Evra changing schedule is now switched to the day that you applied the new one. In this case, you will need a backup contraceptive for 4 weeks.

3. What should I do if a patch seems loose, partially lifts up off my skin, or falls off?


Do not try to re-apply a birth control patch if it is no longer sticky; if it has been stuck to itself or another surface; if it has other material stuck to it; or if it has become loose or has fallen off before.





For less than 24 hours:Try to re-apply your patch or apply a new patch immediately. No back-up contraception is needed and your ';Patch Change Day'; will remain the same.





For more than 24 hours,or if you are not sure for how long: Start a new four-week cycle immediately by applying a new patch. You now have a new Day 1 and a new ';Patch Change Day';. You must use back-up contraception, such as a condom, spermicide or a diaphragm, for the first week of your new cycle because you may become pregnant during this time.





Re-apply the Patch by following these instructions:








Press down firmly on the patch with the palm of your hand for 10 seconds, making sure that the edges stick well. Then run your fingers around the edge of the patch. Do not use tapes or wraps to keep the birth control patch in place.





If the birth control patch does not stick well, remove it and then apply a replacement birth control patch. This patch should be replaced on the original ';Patch Change Day.'; Single replacement patches are available through your pharmacist.





AND THIS:


The patch is very adhesive and rarely comes off. You can go in the shower, swim and exercise whilst wearing. The patch should be applied to clean, dry skin and you should avoid using any creams or lotions near a patch you鈥檙e already wearing to ensure it sticks as much as possible





Thats all I could find - hope it helps! :)
