This so our first cycle back since our MC in early November. We didn't know we had miscarried until after I had ovulated last month. I'm almost glad because it has given me time to feel better about our MC. I haven't gotten a positive ovulation test yet but I don't expect it until Tuesday. We are going back to our parents houses in NY for Christmas but will be driving back to home to VA on the 29th. So I'm wondering when I should test. Christmas Day? I don't know I want to see that BFN on Christmas. But if it's positive it would be the best gift ever.
