When you take your combined pill correctly you won’t ovulate at all, but because you started and stopped and then started again it’s possible you weren’t protected if you had sex before waiting the full week that would be needed to be protected.
While it’s true that you are protected immediately when starting the pill within 5 days of your period starting, you didn’t take enough pills to cover for 3 missed days. Meaning you would start from day 0 on the 9th. With the combined pill it takes 7 full days to become protected, which means by the time you take the 8th pill.
It takes 3-6 months to adjust to the pill, and it’s the time where you will experience most of the side effects if you combine that with being irregular it will likely result into even more side effects, which can explain the bleeding.
It’s impossible to calculate your chances, if you had sex before you were protected from pregnancy. The only way to find out now is to take a pregnancy test. These are most accurate 21 days after unprotected sex. Pulling out is not an effective way to prevent pregnancies, as pre-cum can contain live sperm and is unavoidable. It’s best to use condoms if you’re still unfamiliar with your birth control.
I recommend you use condoms for the foreseeable future until you have had the time to educate yourself on what you’re taking and how to take it properly. Birth control is a big responsibility.
