| Possibly, I've only ever had heart burn when I was pregnant with my son and it didn't start till the second tri and lasted to the end. How I remember it felt was my throat being on fire and having trouble trying to swallow. It's very very annoying. Think that was probaly the worst part lol maybe even worse than labour.
I think it's rolaids you can take, not tums, but maybe someone else can chime in.... |
