I have a question I'm on the depo shot. And I've always been instructed to get it a week before the assigned date or a week after. This is my 4th time getting it and I've always gone a week before the assigned date but this time I went a week after my assigned date was Jan 26 I got it on the 3rd of February. and My period had already ended.. I waited 11 days before me and my boyfriend had unprotected sex. Should I be worried?
