Periods on birthcontrol

Mallory

Hi everyone, I’m not sure if anyone has experienced this before but I just wanted to get some input. I’ve been on the pill for about 3 years now and my prescription got changed to a different brand like 5 months ago and since then I haven’t ever started on time when I was supposed to. I was supposed to start a week ago and I haven’t started bleeding but a couple of days ago when I wiped there was very bright blood on the toilet paper but I’ve had nothing since that...I put a pad on after thinking I was about to start bleeding but I never did... has anyone experienced that?
