Horrible heartburn

Nazaret
I really need some home remedy for this,I've had it my entire pregnancy but it got to the point that it keeps me up all night long(last night till 6.17am)and makes my throat hurts.All I take is Tums but they are not helping and can't take more than 6 in 24h anyway and Zantac(ranitidine)caused me palpitations and sore throat right after taking it so it's not an option.I feel so miserable
