Insemination schedule advice?

I am looking to do my first cycle this month, I ovulate the 27th and am thinking of inseminating the 24th, 26th, 27th. Yes?

I’m using the menstrual cup method with preseed and using a known donor, in case any of that makes a difference (and I have a history of being bonkers fertile!)

I’d love to hear what timing/schedule worked for you!
