ovulating on BCP???

Nisha • Can I help you? 🙄
I was on BC because of irregular periods. I lost some weight and electively came off BC to see how my body would react. Luckily I've been ovulating and menstrating regularly (I'm convinced it was my weight causing the problem). So after 3 months, I went back on BC this time to avoid pregnancy.. But I think that I ovulated this month when I shouldn't have... Hopefully nothing gets fertilized... Does this happen? I'm starting to worry
