Anyone with GERD or just stomach issues?

A❤️C

I was told I have GERD but the majority of my symptoms are stomach pains and tightness/stomach cramps (Not burning but I do have that sometimes) I was taking Zantac before I got pregnant and it was great. I stopped when I found out I was pregnant. I'm only 7 weeks and before now my stomach weirdly wasn't bothering me and now it hit me full force really bad this week. Any recommendations on remedies on what to do? I'm dyinnnnngggg!!!
