Ok, sorry to make this long. but its hard to explain.. according to an ovulation calendar and going by my periods my most fertile days were the 19th through like the 22nd of may. My boyfriend and I had sex on the 19th. well, i had my next period it was 3 days early and I would say normal on the 5th of may. It is now june 15th and I have been feeling a little sick and my nipples feel like they burn.. I know that you can get pregnant outside of ovulation, but I was wondering if the 21st was the most fertile day to get pregnant could it take 2 days to concieve??Any help would be great! thanks
