For the past 2 weeks i have evening to night time nausea. i haven't vomited yet at all. i started my menstrual cycle 2 days ago.?

Nausea: Pregnancy should always be considered in women who might be. Especially if there are any changes to the menstrual pattern or pregnancy symptoms such as nausea. Do a test and get checked by a doctor for stomach or intestinal issues if cycles and hormones seem normal.

Start easy: Try treating reflux with generic zantac (ranitidine) to start; if u get relief stay on it, if not consider other options.
