Quick question

Julie
So lately I've been a lot more hungrier, but it's possible that it could be AF since she's due in about 3-4 days. I have a son that is going to be 1 this February, so it could also be my body still trying to regulate itself. My cycles have been about 35-36 days, and I don't know exactly when I ovulated.. I just know that I'm on CD 33/34 (two different apps). The past couple days I've been having trouble sleeping on my right side and I'm usually okay sleeping on my right side. Just. Now when I do decide to lay on my right side I can't breathe? It's harder to breathe atleast. I'm fine on my left side though. I've been feeling bloated sometimes too, and nauseated in the morning because I'm extra hungry when I wake up. Could it be AF walking in soon? No spotting or anything whatsoever. Or could it be a possible pregnancy? Thanks ladies!
