Hi Ti Lionne. I've never had to provide the first urine of the morning. In fact, all my Ob apppointments have been after work at about 4.45pm and I give the samples there so they are very late in the day samples. I think they only time you need to provide FMU is during a pregnancy test. Give them a call and check but I think you'll be fine.

Good luck with your pregnancy and hope all goes well, it goes soooo fast!
