Hi doc..this is my case, when i was a single my period is regular i don t normally experienced delays or advance period but when i got married my period seems to get irregular. Before my period is 4 to 6 days but now it will last 2 to 3 days and not heavy unlike before. My last period was on July 17 and ended on July 19. I was expecting that my period for this month will be on August 16 or 17 but yesterday (Aug 13) my period came, during the day it was light but on night time it gets heavier until this morning but not so heavy like my usual period. My first question is it normal that the menstruation cycle will change when you got married? My second question is, my period now is implantation bleeding ?
