Primoult N was suggested by a doc on my request to postpone my periods and i have to start them from tomorrow. I have a query before i take medicine, i am having mild lower abdomen pain and lower back pain, similar to what I usually have during my periods. Are these symptoms that my periods are coming? Also i have this pain from past 5 days or so and it is more clear from past 2 days. So i want to know what does this pain means and i should take prescribed tablet for periods postpone or not in this situation.
