Should I test on 7dpo?

Hey,

I have a laparoscopy pre-appointment due soon. The hospital called today to rearrange my pre-assessment to Monday 25th.

I ovulate today so will be 7dpo. I hadn't planned to test until AF was due. Should I test on the 25th just in case?

They will also test on the day of the surgery but I'm just thinking I might be able to let them know earlier?
