What can i take for hearburn while i am pregnant i am 12 weeks and i get really bad heartburn with this pregnancy ?

Tums (calcium carbonate): The safest thing is to chew on es Tums (calcium carbonate) which you can do repeatedly if no relief contact your doctor.

Ranitidine: Ranitidine (zantac) is considered safe in pregnancy (it is available without a prescription); also, calcium based antacids, such as Tums (calcium carbonate) are safe.

Start with tums (calcium carbonate): You can start with Tums or another antacid like it. If that doesn't help, try pepcid (famotidine). If you are still having heartburn, talk to your doctor about prescription medications. Generics here are just fine. You can also try eating smaller, more frequent meals and avoid spicy foods or whatever makes your heartburn worse.
