First Month TTC

My husband and I just started TTC this month and tracked my OV with a OPK and thought we had a pretty good chance...My cycles vary between 24-29 and Glow gave me 2 more days till I start...then AF showed up today.... Feeling blue now... I have an 11yr old from my first marriage and I've had one miscarriage in between....Brand new marriage with new hopes and dreams of starting a family...We could really use some baby dust
