You really need to get a pregnancy test. That is the only way to know with certainty. If you are not pregnant, then in the future make decisions to make sure you don’t get pregnant until you want to. There are many options available to women that keep them from becoming pregnant. My best option was to wait to have sex and sexual contact until I was ready to become pregnant. That way, I knew I was safe, healthy and my marriage is even better because we waited to have sex until we were married. Not everyone wants to wait, and it’s ok to wait from this day forward, no matter what you did yesterday, or a year ago. Make a new decision to take care of your heart and your body. My very best to you, Imajackson;)
