... first 3 days in the patch my boyfriend ejacualted in me. This following week is my 3rd week I'm suppose to change my patch every Thursday but ripped the patch off on Tuesday because the patch was not sticking and later that day my boyfriend ejacualted in me again. I'm extremely nervous because I'm only 18 , this is the week I'm suppose to have a week off the patch so idk if I'm possibly pregnant, if it's a low chance of high chance. If I should be expecting my period in the next few days. I'm highly concerned and need answers
