Labor soon?

I woke up this morning feeling like absolute crap. More tired than usual, extremely nauseous all day, no appetite, decreased fetal movement(still feel her pushing against my belly some), and extreme pressure and back pain.

I’m not positive if it’s true contractions because it’s sort of irregular and non stop so I haven’t timed them. Also having shortness of breath.

Anyone else experienced this and everything been okay? I have a 2.5 year old and a husband works out of town so I can’t just drop everything and head to l&d. Any advice would be great!
