Trying to conceive

Anna
Hello everyone. Me and my husband have been trying to get pregnant since Jan. 2016. That is when i stopped taking my birth control. The struggle feels so real. Any suggestions? I have been taking prenatal vitamins. And we are having sex pretty regularly but still no baby. We have 1 child already that is 3 years old and we think it's time for him to have a sibling. Any advice would be greatly appreciated.
