Having done IVF, no i normally wouldn't.
However my DS was a freak natural conception after years of no contraception and after 3 early IVF losses in 7 months. I was scheduled for an endometrial biopsy and it was only by an inkling i had that i did a pee stick the night before the biopsy at 9dpo and the faintest of faint lines came up. Had I not tested, I would have done the biopsy in the morning and lost him, my one natural miracle.
So in his case, I do feel he was meant to be, against all odds.
