Uterus is playing tricks on me

Kenya

Ok I had my regular period AS SCHEDULED Nov 1-6 then I flew to Korea to visit hubby Nov 11. Of course we immediately did bd as soon as I got here. Then on nov 16 out of literally NOWHERE I start bleeding first day was a weird shade of red. Second day was red brown. The third was light spotting and pink. Then it just stops. Quite frankly idk what to think. Had blood test and all egg production levels were normal. I guess it's the waiting game for me at this point
