Ovarian Surgery

I had 6 mm benign tumor removed on the 16th of May. My anxiety is through the roof. Not only from the cancer scare, but from the healing process. I am in no way wanting a baby for the next year or 2, but Ive only had one period since the surgery and even thinking of peeing on a stick scares the crap out of me... Any one here have any idea for when periods will start leveling out? I'm on the pill and I take it daily as perscribed but my anxiety is just through the roof every month, especially when eve says " your period is ______ days late... This month it should have started yesterday 🤯😰😬
