My fiancé believes I’m pregnant 🙅‍♀️

So we had a date night,and this lady mentioned if I was pregnant ( I just had a baby in august ) in the kitchen he was like I have a feeling ur pregnant

I ask him and said why and he mentioned he had gut feeling..like he did before…funny thing is I found out I was pregnant/or I might of gotten pregnant around this time

I’m terrified I’m not ready for a second baby
