First month insem/BD question

Hi everyone,
​We are a same sex couple using a known donor for at home insemination. This month will be our first round TTC. I've tracked with Glow for about 10 months and used opks. I get a positive opk on the exact day Glow predicts the highest chance (32%). Because we have a flexible donor, should we insem the day before, day of, and day after? Any help would be much appreciated!
