I've been on birth control for a pretty good amount of time now, few months I'm pretty good at remembering and taking on time but I missed the starting pill of a new month so I had an 8 day break. I took 2 pills the next day and the next 3 days on time. I had unprotected sex the next day. It's been 10 days since then and I'm worried that missing 8 days messed me up and I wasnt protected. I've been feeling under the weather since but I think it's just my anxiety. Am I safe??
