Period after pill advice…

I came off my pill in December and my periods are still not normal, I’ve read it can take 6 months to come back but it’s been 6 months now and still not getting any kind of pattern back…

First period (withdrawal) - cycle 30

Second period (first proper period) - cycle 37

Third period - cycle 46

Fourth period - cycle 48

Fifth period - cycle 34

Sixth period - currently waiting on cycle 37
