Hello, I would be happy to help you with your question.
You started taking the birth control pills AFTER the point that you might have conceived. For this reason, you certainly might be pregnant. The pill might have delayed your period, and you need to take another pregnancy
test in one week to make sure whether or not you are pregnant. I am sorry that I cannot tell you for certain - just repeat the test and everything will be clear!
I hope that this helps. If you have more questions, please click on "ASK ME A QUESTION" link above to directly ask me a question!
