Sleep at 12wks dunno

i’m 12 weeks in and sleep’s been all over the place. some nights i’m up every hour, others i sleep 5 hours straight which is kinda unheard of for me rn.

does anyone else experience this unpredictability? i’ve been tracking my sleep and it seems like the nights i have more protein before bed are the ones i sleep more soundly.

idk if it’s a coincidence or what but i’m gonna keep experimenting. anyone have any tips for sleeping better during first tri?
