Ttc month 10

Patricia
Me and my DH have been ttc for 10 months with a miscarriage back in September. I usually start with cramps the day after my fertile week all the way up to AF. I don't have cramps at all now. I also have an OB annual check up on the 20th and my period is due 23rd/24th. Do you think this is our month and will my Ob be able to confirm?
