Hi. My name's Kristina. I've been Trying to conceive for the last two months. I didn't get pregnant last month due to a miscalculation in my ovulation date. My last menstrual period was January 27th, 2012. I had sex yesterday night, Tuesday, February 7th, 2012. I'm supposed to ovulate on Friday, February 10th, 2012 . Is it possible the sperm still has a chance to meet with my egg or do I need to have sex again to ensure pregnancy?
