Did I just get pregnant !!! Wanna know ur experience !

Hi ladies I would like to know if you remeber around the time you ovulated after having sex if you remeber feeling any different and it actually turned out you were pregnant I ask because i had sex on my 7.4% day but certain i ovulated yesterday due to cm and cramping last night and all today I have been feeling quiet sick but more so last night could there be a chance of being pregnant if i only had sex on my 7.4% day could the sperm live in there long enough to get pregnant!
