I am a 19yr old female on the Patch. Before I had my last period, on the day which was supposed to be the patch free day (I was on my third patch already) the app was telling me to put on a new patch (on September 19th) and said my period wasn’t supposed to be until the first week of october. I didn’t put a new patch on and ended up getting my period as usual a couple days later. However, I woke up this morning (October 6) and got it again, I had just gotten it exactly two weeks ago today. (Sept 22) I just don’t know if the app was right that I was supposed to put a fourth patch on for some reason or something else is going on. Thank you for reading!
