Hello and Welcome to ‘Ask A Doctor’ service.
I have reviewed your query and here is my advice.
Your age and history of menstrual cycle are important. Your problems are chronic
gas problem in stomach, not active for the last few months, stomach virus few days back, delayed last period.
Long-term (chronic) gas problem may be due to
peptic ulcer, your food and food habits. Change of food and food habits and treatment of peptic ulcer will make you alright.
Delayed period need not be due to stomach virus. Better to wait for few more days.
Not active for so many months may be due to all the 3 medicines you have mentioned.
First, analyze and meditate yourself if you are having
depression.
Hope I have answered your query. Let me know if I can assist you further.
Regards,
Dr. S. Jegadeesan
