ok so my gf and i had "intercourse" on the 4th of february. i didnt penetrate nor get past her hymen and i did NOT ejaculate inside her but im afraid that she might have goten pregnant from pre-ejaculate. well i know that the chances of pregnancy are at its highest when the woman is ovulating, therefore if she had her last period on january 13th and her cycles usually last 28-31 days that means she ovulated aproximately on the 27th of january or the 26th of january.this leaves a gap of 5-8 days before we had "intercourse" on the 4th of february. knowing that the egg has to be fertilized 3 days after it is released (26th -27th of january aproximately), and knowing that the egg desintegrates after that time .could it be possible that at the time of "intercourse" there was an egg present ?. my gf said that on the 9th of february(5 days after "intercourse") she felt a small cramp similar to the cramps she gets on her period but less painful, and on the 8th of february(4 days after "intercourse") her nipples were a little sensitive to the touch. she expects her period on the 11th - 14th of february(she had never felt these things before) could these be pregnancy symptoms, or just pre-menstrual symptoms?
