Does Taking Modus Progestrone Help In Getting Delayed Periods?

hi,i had my periods on 14th jan and then i had an intercourse on 25th of jan then again i had it on 11th feb...maybe due to that i missed my periods..and then i took the pregnancy tester kit, it was negative but still for my saticfaction i took MTP.......it didn't help in any way...i didn't get my periods even after taking that......so i took regestrone for 5days from 24th-28th feb....it also didn't help.. then i consulted the doctor n she suggested me modus progestrone for 5day..... So i just wanted to ask that will it be helpful this time ?? i checked it twice on tester and it was negative
