Unfortunately as you’ve missed that many pills, your body started adjusting off the pill, and now you’re back on, it’s trying to adjust back on. Basically your hormones are allllllll over the place rn. The adjustment phase of the pill is 3 months.
It’s totally normal to experience heightened side effects like irregular bleeding, mood swings, cramps etc during this time.
There’s not much you can do, you might just have to wait it out and give your body time to adjust.
