Okay, me and my boyfriend had unprotected sex the 28th (last day of my period) &&, he came in me once. We also had sex on the 31st and he came in me twice that night. According to my Calender, i ovulated on the 3rd . Lately I've been really sleepy and tired, and I'm not as hungry as i usually am. Certain smells make me nauseous, also ... my period isn't due until the 15th, but I'm so curious and excited to take a test and see if I'm pregnant! Its too early to do that yet, so I'm asking for opinions ... could i be pregnant???
