Not an expert on this - I've been taking the 1/10 for 9 weeks - but you bleed in the oestrogen bit, not the progesterone bit. So you'll get a bleed again probably in the first week of the oestrogen-only. As far as I can see that's fine, just carry on taking it. It's designed for peri, isn't it, when your own hormones can decide they're feeling left out and it's time to party.
