very bad heartburn acid reflux 18 weeks & feeling something at my stomach

been eating slowly, smaller meals all but still get acid reflux and it hurts so much. i thought 2nd trimester would be a breeze 😭 is eno,gaviscon okay to take if i really cannot endure it? and aniways i havent felt the baby moving. but sometimes when i get up too fast or shift my body too fast i will feel something like a hard kick in my stomach, is that the baby 😂😂 totally forgot how its suppose to feel like cause my child is now 7 yrs old. so this 2nd pregnancy feels like the 1st. #advicepls
