Ah, you're a lucky lady not to go through IVF! It's not too bad for some but I wish it happened the good 'ol fashioned way for us! Well, maybe you O'd a little bit later this month?? I always had spot on 29 day cycles, but in my second IVF cycle which was a natural FET cycle, we waited patiently for O and I actually O'd really early around day 12 by memory. But, as I was tracking my O leading up to that natural cycle, in one of them I O'd on day 17!! So maybe I never really O'd spot on day 14-15 like I thought! GL sweetie
