Iv heard it's not ideal to sleep on your back. Does this apply for all trimesters or just later on? I'm almost 12 weeks and I use guided meditations to help me fall asleep when my mind is busy, but it's very uncomfortable to lay on headphones so I find falling asleep on my back to be easier. I haven't t needed to use the meditation since iv been pregnant till now, and now I'm scared of falling asleep on my back. Can some one just clarify if back sleeping is safe or not at this point. I'm a FTM and you can say I'm paranoid lol
