Birth control help please
So my wife has been on the birth control, minesse. She had a slight runny stomach about 1 and a half weeks ago. She started an antibiotic on a 5 day course from 28/07 to 01/08. She was supposed to get her period now and she's on the inactive pills on her tray.
She's on the 6th inactive pill now and still hasn't got her period. We realized she was on antibiotics and got a plan b which she took on 02/08.
She has however been getting slower periods and she said her last period was 3 days later and she barely even bled at all. We did a pregnancy test the day she took the plan b and it was negative but maybe it was too early to be accurate.
I'm unsure of what's going on and her and I just want some help if possible.
