Hey there, Anytime you engage in sexual activity, protected or not you can run the risk of pregnancy….Sure it can help to know your ovulation times but they can also be unpredictable and altered by hormone changes so it is always better to be safe than sorry and avoid sexual contact if you wish to not risk pregnancy…..The best way for you to rule out pregnancy and get peace of mind is to take a pregnancy test….Go ahead and visit, http://optionline.org/ , If you enter your postal code into the site it will give you the contact info for the closest Pregnancy Help Center to you where you can get a FREE and CONFIDENTIAL test! I hope this helps and if you are up for it, come back and let us know what you find out! Much Love….Meg
