General period/birth control talk

I changed my diet to a limited dairy pescatarian, i stopped drinking any sodas and juice besides 100% unsweetened cranberry and kombucha, i also limit my carb and sugar/salt intake. I was on Estarylla after being switched for no reason from MonoNessa and it was terrible.. both birth control pills caused me to gain a total of 70 pounds. i stopped taking birth control back in March/April and started my new dietary plan back in June. I lost 30 lbs since June and my period finally came, but it’s unusually heavy. is it possibly making up for lost time? or is it because i sort of “reset” my body?

i remember when i was in grade school i had heavy flows but ever since i started birth control they were very light and as the years progressed they became almost non existent, i’d be lucky to get some spotting. i’m definitely making an appointment with a doctor but i wanted to know if anyone else has had this problem and is there a birth control that won’t break me out and cause me to blow back up?
