I was on Sprintec but switched to Microgestin which has fewer hormones. I had my period the 27th to the 31st during the placebo week of my last Sprintec pack. On the 1st I started Microgestin. Yesterday (the 8th) I started having some light bleeding that has continued into today (although it’s lightening up even more so I think it’s just about over). I’ve taken my pill every day at the same time but yesterday took it 45 minutes later than usual. I have a feeling it’s ovulation bleeding since my body is used to the amount of hormones in the Sprintec and now has much fewer hormones and I got a pain in my ovary yesterday which usually happens to me around the time of ovulation. I’m just wondering if it is ovulation bleeding, when am I no longer fertile? I know it might not be ovulation bleeding but I don’t want to take the risk that it is.
