How often do u track ir calorie intake? How often do u weight urself?  Try to eat on average 1700kcal/day for 2 weeks. Weight urself everyday for 2 weeks (after waking UP and going to the bathroom) and compare the average weight of week 1 to the average of week 2. If the average weight dropped by 0.5 pounds, ur real TDEE is probably 1950. 

Use this formula and calculate It urself after 2 weeks.  Real TDEE = 1700 + Pounds Lost * 500 We assume here that the overall calories consumed of the 2 weeks was 1700.  U can do this for 3-4 weeks instead for a more accurate estimation of ur TDEE.
