Hello, Im planning to go on a vacation and its mainly diving, so i urgently need to postpone my period. I have my period now and its due 27 of june which is the begging of my 6 days trip. However, when i used norethisterone before i got all the side effects. I was in alot of pain, bloated and in horrible mood and my period didnt regulate for almost 6months after taking norethisterone. I m not on the pill so i cant do the alternative method. Please advice if there is any other way and if its only norethisterone that can help, which tablets are the best with minimal side effects? I hope i wont have to go with norethisterone and i hope you find another way. Thanks alot
