Frozen Sperm and 1st IUI Attempt- Need ADVICE

[BKmama]

Hi! So after 3 months of trying with fresh sperm and a syringe and Instead cup with good timing but a cranky donor... we are changing things up. We are now trying this month with frozen sperm from PRS and doing IUI. We ordered two vials to be delivered tomorrow but got our +LH surge early this morning. Our midwife is suggesting that we just try one because we should have done one this evening but now we can only do one tomorrow afternoon which seems to put us right at the end of the 24-36hr period. Sigh. I'm frustrated but happy we are atleast doing one...but really want to do thursday as well. What do you think??? Should I save the extra vial or give it a go..?
