Heartburn & ingestion.

I will be 25 weeks on Thursday and I've been having the worst heartburn and ingestion lately..

I sure hope baby Zoei comes out with a full head of hair I've been taking tums but the kind I had is kind of nasty (fiancés mother got them for me) i was told not to take any that have aluminum in them or aspirin so the they are in fact pretty nasty and chalky I don't like milk so that's not an option for me it makes me gag I've tried so any other things you can do for it? It seems to happen when I'm trying to go to bed or after a meal.. I've also been waking up nauseous a bit from it.
