When to inseminate?

So in April our donor will be available to do two donations, when would be the best time to do them?

1) Day before and day after Ovulation

2) Before and day of Ovulation

3) Day of and day after Ovulation

We concieved our daughter using one donation on the day of Ovulation but that hasn't been working for the last 8months or so!

Thanks 😊
