... until Saturday instead of taking it off for my patch free week, normally when I take my patch of it starts straight away on a Sunday morning (like clockwork never been monday or Tuesday). i have had sex without a condom but with no ejaculation, am I worrying over nothing with my late period or is it because I left it on too long? Even tho I left it on too long surely the hormones on the patch had already been used up and wouldn't delay my period
