hopefully

Soooooo my period was on the 28th and so I've been trying to have sex as much as possible on the 3rd did it in the morning and at night and Sunday at night almost midnight . Hopefully I conceive this month. What do you think are my chances ? I looked up how many days after your period how I be fertile and it's says 10-17 . I'm on day 11! Any advice ? Comments ? Pleae and thank you :) I'm praying for a positive this month .
