Keep forgetting to take pill at correct time.

Hi.

I’m taking microgynon-30 contraceptive pill.

I’ve been taking it for 2 months now, the first month was every night at 7 then I had 1 week break and started a new pack. However with this pack I have forgotten 2 pills and the rest I take between 7pm-12.(4 hours apart).

I have 2 children so sometimes I am busy and forget to take my pill. I usually have an alarm set for a reminder but if I’m busy I just think ‘I’ll take it later’ and forget until a few hours later.

Will my pill be less effective if I’m not taking it at the correct time each night? We’re not too bothered about pregnancy but would rather not at the moment.
