No.
The most fertile time is after she has ovulated (about 8-10 days after the first day of her period).
It is possible to get pregnant at any time during the cycle though. Every woman is different.
Hope this helps.

wait do u mean 8-10 days after the last day of her period? how can she be most fertile if the egg is already being get rid of.

ok sorry ovulation is usually at day 12-14.
Day 1 = first day of her period.
The egg is released after her period is over.

is ovulation a fancy way of saying "egg releasing"? sorry im not good with this stuff. Im trying to educate myself more. So ovulation is 12-14 days after the first day of her period?

yes

if i want to get my girlfriend pregnant ? how do i know what day is the best to try ?
