Sad and confused

So for the past couple of weeks I’ve been absolutely exhausted, i sleep more than usual, I’ve done nothing but eat basically every hour for like a week and a half now, my cravings are whack, my nipples are a little sensitive, I’ve had a change in sex drive (it’s usually down but it’s been up a lot recently), I’m 14 DPO, my period was supposed to start yesterday and i took a test first thing in the morning but i got a BFN...I’m sad because my fiancé and i really want this baby and my body is totally sending mixed signals. Help...? What do y’all think. Take another test or..?!

Update. I just got my period. We’ll try again next month
