OK.. i know nothing about heartburn. Is this what I have??

I've got a general discomfort leading up to my throat.. but I wouldnt' describe it as burning. Lying down with DS just now putting him to sleep, I had a bit of reflux and thought yuck!

I've had this the last couple of days. But today I've been feeling pretty off, as if my sugar levels are fluctuating - feel better when I eat - but I seem to have this constant discomfort, and constant little burps!

Is this heartburn? What can I take? We have some mylanta, but the site says to ask my dr if pg or breastfeeding before taking it, and I'm both. I'm dreading going to sleep tonight now, coz I don't wanna be burping up stomach acid!

Any advice is greatly appreciated!
