hello, i am 29 yrs old. last november 21, 2011, i thought i will have my period since i started spotting. but i only have spotting until december 25 when i got my period. the blood coming out from me is thick and mostly round.. the period stopped january 1 and continuously i have spotting. it never stopped. the doctor prescribed Tranexamic Acid for 3 x a day for 3 days. after that, the bleeding didnt stopped so she prescribed Primolut N. i am now in my 2nd day and no spotting has occured. do i have to finish all 30 tablets?
