About 10-12 days before my TOM, I get super tight and have a sour stomach. Not exactly reflux, because there's no burning sensation. More like a bad taste in the mouth. It lasts about a week. Not sure what to do or if I should see my doc. Any thoughts?

When in doubt, I always side with caution. It can't hurt to mention it to your doctor and get their opinion.

10-12 days prior seems too soon for TOM issues. Perhaps it's the hormone increase during ovulation?

I'm just getting back on track from having a baby, and this is new. I'm hoping it will go away!! I'll ask, thanks for responding.
