pregnancy

Im trying to get pregnant been tracking my ovulation and all. Been trying for 3 months but this past weekend. I had intercourse 3 time, 3 different days & all on my highest peak of ovulation. Well if i dont get my "monthly visit " on the 9 , i should be pregnant correct? And if im not, what other ways can i try to become pregnant? Ive been pregnant in the past have a 3 yr old but now thh im trying it isn't happening and im getting kinda scared. I really want another baby.
