hi good morng..I got my period on 24th last months. For two months I am getting period on 24th regularly.Earlier I got adjectly on date but due to my thyroid problem now its irregular dates. I want to postpone my period this time as I am scared that I may get before 24th as I have some functions at home(21-23). I do have abdominal problem on periods. What kind of tablet should I take. Is Familon ok?Kindly suggest.
