Any doctors on here?

Hello so I need help and have no one to turn to.

I’m on the combination, hormonal birth control pill and I take it every day at 9:45 exactly. Haven’t had any issues in the past.

However, this month I had to go on prednisone to take down some swelling in my vocal chords, I wasn’t on antibiotics or anything like that though.

Does prednisone have any interactions with the pill. I’ve been having a very mild headache for the past few days but I can’t tell if it’s because I’ve fallen pregnant or if I tapered off the prednisone incorrectly (which did happen) I was on it for nearly two weeks.

Thanks!
