i am 6 months pregnant

Yes mommy. Sabi ni OB mas malaki na kasi ang uterus especially during 2nd and 3rd trimester. It’s taking up more space sa tummy natin and it’s putting pressure sa diaphragm kaya mahirap huminga lalo na if naka higa ka ng flat on your back. Try to elevate likod mo paghiga and as already mentioned by others on your left side ka magsleep.
