Period

I’ve been on the same pill for about 3-4 years. I stopped taking it for about 2 months at the end of last year and started taking it again at the beginning of this year. This is my first period back on the pill and my flow is very very heavy. Could that be because I forgot to take 2 of the low dose pills? Even not on bc I’ve never had a heavy flow so it’s very different for me.
