BD now or tonight?

I took an OPK 24 hours ago and it had an extremely faint line. Took one just now and the test line turned positive before it even reached the control line. I didn't expect to ovulate until tomorrow so DH and I did a release last night (this month we switched to him releasing every 2-4 days). Do I have him come home at lunch to BD or do we wait until tonight? I don't know how long it will stay positive.

I'm sure either way would work fine!

Either way. IF your test has just gone positive you won't ovulate till tomorrow anyway.

IT doesn't matter how long it stays positive. That has no bearing on when you ovulate.
