Hi Everyone. 3 months ago I switched from the combination pill to the progestin only pill. I just started my third pack of progestin only, and was supposed to have already had my period, but it’s 7 days late. My first month of my progestin only pack, I had my period like normal, but it was heavier and more painful that usual. This month, I bled for one day, 6 days before my period was supposed to start, and then my actual period never came. Anyone have any experience with this? I take my pill religiously, never late, never missed. Thanks.
