Short period ? Not normal!

Hey!

I’m on the pill and have been for over 2 years now. But this month, I had one day where I was late by 12 hours and then accidentally took 2 the next day (so 3 in total, on two days). Right now, I got my period and I was rather heavy (about 2-3 pads, so one per day) and now my period seems to have stopped. It usually lasts 5-6 days and it’s only been 3 days ? I’m not sure if it will pick back up but I’m worried about wether or not I should suspect pregnancy (although 1 pad a day worth of bleeding might indicate otherwise) or some other problem.

What do you all think? My doctor’s appointment is in a week and I’d appreciate some ideas until then.

Thank you!
