Hi, Thanks for posting in HCM. I understand your concern. Since you have had periods and following which you did not indulge in intercourse, there is no chance to be pregnant. You might be having irregular periods as you could be approaching towards menopause. You can consult Gynecologist to undergo clinical evaluation and undertake certain laboratory tests if suggested. For your acid reflux, you can take medications like Famotidine or Rabiprazole once a day for about a week to ten days to overcome it. Kindly do not eat spicy and oily foods as this would exaggerate the symptoms. Hope the information provided would be helpful. All the best.
