Newbie Question

Emily
I'm 39 years old and just starting TTC for the first time..a little overwhelmed...I stopped my BCP on 2/22 (mid pack) and my period started on 2/25 (about 5 days before my normal start day) will this change my ovulation time being that I just went off the pill and I know it takes time for cycles to regulate....just looking for some insite when would be the best time to TTC....thanks!
