Taking the pill, and been bleeding for two weeks now - hormone dose too low? Pills too old? - low hormone pill

Hello ladies (or men well informed), I started to not take the pill after years. I started taking the pill on the first day of my time and must take every day, to keep trying in the morning. And although my pace was very easy, has not ceased. Is it likely that this hormone is too low for me? I realized that these tablets are dated to expire soon. Is it because the pads are too old? Thank you.
