Taking then not taking the pill

Hey guys,

Looking for some help

I’ve been on and off the contraceptive pill since I was 15 so five years.

I stay on it for months and then come off for months which I probably shouldn’t be doing?

Could anyone tell me if this could be causing me any harm that I’m just not aware of?

My periods a bit fucked up now coz it comes every 7 weeks without the pill but if I’m on the pill it regulates it so I’m thinking about going back on it again.

I’ve been gettin packs of friends and family so according to the doctor I’ve not been on it for about a year 😂
