Same with me on my last pregnancy. Severe heartburn. Usually heartburn happens when pregnancy mom got high bp. But not all heartburn related to high bp. In my case, I got high bp that time, fasting some more and heartburn became severe + dehydrated. Doc advised me to break my fasting and drip 2 bottles of water. Alhamdulillah. Nothing serious. Just please let your doc know about it. So they can do the necessary. Take care !
