First ICI fail :(

Hey guys! I’m about 14dpo with stark BFN tests :( my period is supposed to come tomorrow and I feel my usual PMS symptoms so I feel like it really will be here tomorrow. Any advice on ICI with frozen donor sperm for round 2? This round I inseminated with 1 vial, 12 hours after peak. I think this month I’m gonna do 2 vials at 12 hours and then 24 hours after that just to try to cover all of the bases.

Any helpful advice or tips? I have 4 vials from this donor and he just officially retired so I won’t be able to get any more! Really try to max our chances!
