I made a huge mistake, yesterday was the 14th day after my cycle, I used the ovulation calendar and yesterday was my MOST fertile day...I'm on the pill, and I've been on the pill for about 6 months. Now, last night my boyfriend stuck a little part of the head in my vagina, he had NO PRE CUM and it wasn't even a full boner (still kind of soft). Is there any chance I could be pregnant? I'm feeling pain in my ovaries, but I'm almost positive those pains are my ovulating pains ( i always get cramps while ovulating )

My boyfriend says there is NO WAY Im pregnant since the whole head wasn't even in, is this true? Please reply, I want to stop stressing over it...since my period won't start again for another 12 days..I don't want to be worried for 12 days! Thanks! :'(
