Product recommendations and help with understanding BBT

Candace

Hello! Husband and I are TTC#1 and have very recently started this journey. I’ve been using the <a href="https://play.google.com/store/apps/details?id=com.glow.android">Glow App</a>, along with 3-4 others to try and gauge my fertile window. I’ve also been using OPKs for the past 2 cycles. I don’t currently BBT because I work nights so I’m usually up late (3-4am) and wake late (12-1pm). From what I can tell it’s best done early in the morning? But my rhythm sort of is misaligned with that. I could certainly wake early just for the temp, but I genuinely didn’t know if only sleeping for 3-4hrs would skew results? Or can I just temp whenever I wake? I’m also just looking for any products people have used they feel greatly increased their chances and might have aided in becoming pregnant. Thanks!
