Advice needed!!! The pill

Hey guys. quick forewarning here.. this might be a little gross. i’ve been on birth control since i was 18. im now 21 and i’ve been on it the whole time besides maybe half a year when i was 18-19. the pill i take is alesse which is a combination pill. i usually skip the placebo week and start the next pack. but the issue is whether i wait the week or don’t i never get a real period. most people would love this, but i still bleed. it’s at random times and completely unpredictable and it’s always old, brown, and clotted blood :/ i’ve tried waiting the week but i still don’t get a regular period. i’m thinking of taking a break from my birth control and waiting until i get a regular period and then starting it again but i am worried about my hormones being weird from stopping. before birth control my periods were very heavy but regular. they have pretty much never been regular since ive started birth control. i don’t want to try a higher dose because i don’t want to gain weight or experience other awful symptoms. what should i do:/
