EVERYTHING I eat makes my stomach hurt

Chalese • Wife & Mother❤ I have 2 beautiful girls(6 and 1). I have had 2 miscarriages and am currently pregnant with our 3rd girl!!!
I don't eat=I'm sick/ I eat=I'm sick
I haven't thrown up yet but the nausea is real...I constantly have an upset stomach/heart burn that makes me super nauseous and I gag at every strong or stinky smell😢😢
