I'm 18 weeks pregnant now and I'm having a heartburn that can last until the next day. Is it normal?

Ive had heartburn, sometimes persistent, but not until next day (Im 20+ weeks now). From my observation, diet plays a part. (obv pregnancy does cause it as well). I notice my trigger is overly spicy food or cili padi (Im a hardcore spicy lover), eating too much, drinking sweet or carbonated drinks, or even fast food. what helps when Im hit with heartburn is drinking plain room temp water, lying down, putting a pause on eating until it fades, medications. passing gas or passing motion helps too because I guess its correlated with indigestion and constipation. So try to pass gas or get your bladder going 😅😂 hope I helped
