How long for period/hormones to go back to normal after you come of the mini pill

I stopped taking my mini pill due to it giving me bad anxiety I bled about 2/3 weeks after stopping it's been about 4 weeks since I bled and ibe been having PMS and some other symptoms (spotting sometimes when I go for a poo but it is from vagina) my question is does it take a while for body to return to normal after stopping? I took a pregnancy test to make sure I wasnt pregnant
