Emotions

Anyone else randomly start bawling your eyes out? I was sitting in my chair on my laptop when I just started crying. Out of nowhere. I think I've entered the stage where I just don't feel like myself. I'm so excited about baby!....but I'm getting frustrated with not being myself. I can't stand for too long, can't sit for too long, can't sleep straight through the night, can't move in bed like I used too, can't have sex like I used to, can't remember things like I used to, etc. I'm wondering if it's the third trimester emotions hitting or if it's just an off day haha it's not a fun feeling
