I'm a little worried. My husband isn't home, and the last couple of hours I've been having heart palpitations and trouble breathing. It feels like I have a huge weight on my chest, and I can't get quite enough air. I've had this a couple times in the past couple of weeks but it's lasting a long time today (like an hour).
I'm really stressed out right now with TTC and school and work issues, but I'm not sure if this is stress related or what...

Thoughts?
