fell off in week 3 and I didn't notice until it was time to take it off and it wasn't there. I don't know how long it was off and I didn't start my period yet. If I took it off the right time I would have started mu period today, but I didn't. Should I take a test or wait longer?
That u may have ovulated. From the time it went missing until u get the cycle back on track u may still populate r use protection for now.
My advice is check the clothing u wore in the past few days, it may be stuck on a pair of underwear or a shirt or whatever. Then u can pinpoint when it came off, just for piece of mind. Good luck.
