Me and my boyfriend have never FULLY had sex, but he has penetrated inside of me.. Nothing more than a LITTLE past the tip of his penis. He always pulls out though. I usually mark my period on my phone calender, but I recently reset my phone and lost the data. I feel that there has been a lot of time since I've had my period.. To much time (No longer than about a month though) I thought i would wait until about the 15th of January to get serious about it, but i wanted to know the likelihood of pregnancy in my situation because I am VERY nervous. Thank you.
