should I be worried ?

Does my period pattern seem strange to anyone ? Maybe similar to some ? Or is this normal for "irregular" women 
I'm 21 TTC since I was 18
Took birth control from age 13-18 (while on BC I did not menstrate for the first 2 1/2 years) 
My doctor told me I was on birth control for too long and too young yet all she wanted to do was give me MORE birth control ?? 
I have only had one period so far for 2017
 took 4 tests in march All negative
