We had sex 2 times last week on Wednesday and Saturday , we did it in her most fertile days which were from Tuesday until Sunday of last week, we want to have a baby and I'd like to know what are the chances of her getting pregnant?
Here is the information of her cycle just in case we are wrong about calculating her most fertile days:
May 19 first day of period
Menstruation 8 to 9 days
Cycle length 22 days

Us women have about a 24 to 36 hour window of conception each month.

You should also keep in mind that it takes the average couple as long as a year of actively trying before actually conceiving.

In all honesty, we can't give you a percentage of whether she has conceived. Ovulation, for those of us outside of the fallopian tube, is only a guess.

In the meantime, she should be taking a prenatal/antenatal vitamin, if she is not, to prevent neural tube defects in the fetus should she become pregnant. These should be taken by all women of childbearing years.
