Feeling pressure to do conceive

Vanessa
Ok so I am 27 and have 2 kids 8 and 4 . My fiancé is 35 and has none and he does want children. I am not saying I do not want any. Although for some time I didn't think I did. We discussed it and we decided to try. This is our second month trying. I already felt sad last month when I AF came. But we did have sex a day or so past ovulation do the chances were low anyway. But I'm thinking that if my AF doesn't come this time I'm going to be extra heart broken and even more so because I know he wants nothing more than to have a baby. He's purposely waited for the right time in life and he feels as if is now. And I do feel a bit more pressured because if this 😔
