Heavy periods

I started my period when I was 13 years old and I’m like 16 soon to be 17 in like one and ahalf weeks and my periods are weird and heavy and I had to change birth control pills because it wasn’t working out for me Monnessa because it was not helping my PMS mood swings nor my cramps I think to be honest I just grew out of it and every time I take it my hormones would just escalate I would have really weird cycles I really didn’t have a set date so now this week until Sunday I’m not on any pills and then Sunday I start a new birth control pill Yaz which I hear helps with PMS that’s the main reason I changed because I struggle with anxiety and I found that monnessa made my period Much worse in every aspect of it so I’m hoping my new birth control pills are better in terms of PMS and regulating the flow of it more and the cramps, nausea etc. Who else struggles with irregular periods and horrible side effects from your hormones?
