I was on yaz for almost 4 months and stopped, a week later i took depo injection and had unprotected sex a day later. can i be pregnant?

Maybe: Once you stop taking the oral contraceptive pills daily, the amount of hormone rapidly drops within your body and your body begins to adjust to its normal cycle. Depending on where you are in your cycle, it’s possible to ovulate and become pregnant. When you start a new birth control method, it takes up to 10 days for the hormones to regulate your cycle, so you should use alternate forms of BC.
