Late period??

Lacey • Mama to Ocean Zari 09.28.18💗 & Ollie Zander 05.22.20💙 Luna La’Rae 07.09.22💖

So obviously I have some what irregular periods, I started taking a new birth control (from mini pill to combination birth control pill) do you think there’s a chance I could be pregnant or just a symptom on a new BC?
