Im so confused

Erika • Im 27& my boyfriend is 31. We are trying for our first child together. I myself have 2 children a son who just turned 6 & my daughter will be 5 . im hoping this app helps us have our 3rd child .

I never tried to get pregnant before and all this lingo is soooooo confusing.

Can someone in plain terms tell me when I shld try and get pregnant ?

Like this month my period was 1-6th and its usually 27-28 days b4 the next cycle.

So when shld we try the most. I set up this app hoping it helps .but still so many terms I've never heard nor do I understand!
