So I accidentally left my patches in the car for maybe 2-3 hours and idk how hot it was outside are they still effective? I'm kinda worried i have had condom-less sex after my break week Im worried I wasnt protected and messed up. I'm having lower back aches, sleepiness and my feet hurt. My break week is a week from today. I'm really worried and I accidentally put my patch halfway on my shoulder also so idk if the sun and where I put it just made it less effective...I'm really worried right now.
