I feel like screaming , crying & giving up 😭Helppppppppp

My SO and I BD almost every day of my fertile window 😭 I'm so sad !!! My SO really wants a child ... yesterday he took his nephew to the park and took a lot of nice pics .. when he sent them to me It felt like my heart dropped ! I know he will be a good father 😖😭😭 smh !!!! This is crazy !!!!! I thought this was our month ! Y'all I'm so sad and feel worthless ! We've been trying on and off for a year since I had a miscarriage last year ... AF is here and I feel so sad ! Is there anything I can start doing to increase my chances for next month
