Yeah, it could because maybe you had a light blanket, maybe your mouth was open, etc. There are so many factors so take temping with a grain of salt. Nothing is perfect. Try not to worry about the temp. Look at the whole picture! That's what I've definitely learned. My first was conceived when I thought I was out of my fertile period because I didn't fully understand opks and temping was too hard with working night shift three days a week. Now that I temp and track symptoms and opks, it's much more accurate. I hope this next month is a BFP and everything works out perfect on your donor's side too.
