So tired but don’t want to drink coffee

Jill • Happily married, had my first son 12/31/16 (conceived via IVF), ready to expand my family!

I am 5dp5dt and I am tired all the time. I have cut out coffee and caffeine until I hear the heartbeat. I will drink coffee if i get pregnant but at the beginning I like to be careful and healthy. Any suggestions to stay awake? So sleepy all the time!! 😴
