I've come home for 3 weeks and left my third pill packet at uni. So I've decided I'm just going to have a month off the pill. I was supposed to start my third pill packet on friday but obviously I couldn't and I've had some bleeding since, even though I had my period on my 7 day break at the begining of the week (I always have it at the same time). I'm not sure what this means, could someone please help? Thank you!
