I tested at day 7 and 10 DP IUI and both were BFN. Now it is 12DP IUI. I dont know when to officially consider AF late. This round i did ovulate on day 14 or there abouts and usually it is around day 23 or so. Is it possible this will be a 28 day cycle. I just woke up feeling very nauseas but i think that me over analyzing.
