Hi. I usually get my periods in 28-29 days or sometimes 30 days and never had any issue with it. From the last 4 days, I have been eating papaya, sesame seeds, jaggery, etc. To prepare my periods but did not get it till today. Its the 29th day today and I will be traveling tomorrow. Now I want to desperately stop them as its coming in the way of my travel plans. I took one medicine in the morning'norethisterone - 5 mg. Do I take that 3 times from today or one is enough? Will it be effective since I am having it around my periods date? Is it safe to have it like this? Pl advise what I should be doing. Thanks.
