Hey goodnight, so i?ve been having irregular period since early up last year?. But normally I does take ibuprofen for the 5 days then my period does go away?. So in november/december I received my 2 doses of the vaccine and after my period was late. Then it came eventually when it do came I took my ibuprofen for the 5 days (taking ibuprofen while on my period causes my period to last for the 5 days that?s how long my period lasts for and if I don?t take the ibuprofen my period is gonna remain on me) so after the vaccine when it came I took the ibuprofen and it last for 5 days then went away? but my problem is that it came back like 1-2 days after it left and it?s on me right now from since the 22nd december what do you think I should do or what do you recommend?
