It's fine to sleep on your stomach until it becomes uncomfortable. You'll be tired for a while but it will ease up one you hit second trimester.
Yeah I play on my phone it makes me tired but I just Sean to be awake most of the night
Anf your sleep during the night have some warm milk and read or play on your phne while laying n bed until your sleepy its what i do
Yeah its fine sleeping basically on your stomach is safer then being on your back when your bigger its bad to sleep on back because of blood flow ect but yes its okay to sleep on your stomach side, congrats and its totally normal to be tired constantly just make sure durng the day if you are tired just have a rest
