Talk to Gynecologist on Gynae (menstruation And Pregnancy)

I am 26 yo. Married since 4 months. Been Overweight my whole life but since last 2 years i hve lost 10-12 kgs gradually. Still overweight but not what i used to be. My cycles are regular 32 -34 days long.. But now i am experiencing bleeding at 25th day of my cycle !? Is it normal or what should i do.

( i hve been checked for PCOS twice in my whole life when i was a teen. But everything was normal )
