New to Combination Pill, when will my cycle regulate?

hi everyone, it’s my second month taking the combination pill and i was just wondering if this was normal.

last month i had spotting on my last week of the actual pill, and then when i was taking the placebo pills i also had spotting but it was much heavier so i marked it as my period.

this month the same thing happened, i have two pills left for this month and i have spotting/light pink bleeding.

when should my cycle get to normal? before the pill my period came like clockwork & i almost never had spotting. should i call my gynecologist?

thanks!!
