Can you ladies help figure out what's happening with me?

I think I'm having acid reflux for the first time ever, I have never had it before, and never got it with either pregnancy!

I woke up at 2am feeling like there was a lump in my throat, and some burning sensations... Felt like what I imagine indigestion/acid reflux would feel like. I got up and sat up for a couple of hours, had some milk and some water with baking soda - didn't have any TUMS, bought some today.

After a couple hours felt better, got back to sleep. Woke up with the same feeling and now it's 2pm and I can still feel it - like a burning in my chest and when I drink I have to burp a little to make room (if that makes sense)... like there is still a block in the bottom of. my throat.

Is this normal acid reflux/gerd???? What the heck.

I did eat a larger-than-normal dinner of pasta with red sauce and meatballs, and after bathing the kids and putting the younger one down I laid down in my bed on my phone for a while before going to sleep really early - so I laid down pretty quickly after eating... I've never had this reaction to pasta sauce but know it can happen... just seems weird that I'm still having symptoms this long after.
