Period after baby???

Im just wondering when some of you got your period after giving birth, my labour was quick and easy no complications my sons now 11weeks ans still nothing? Im bottle feeding. I always feel wet down there and have alot of discharge i went to the dr but he said its all normal it should come within the next 3 weeks but maybe about 1-2 weeks ago i had some discharge and it was slightly pink but after that nothing🤷🏼‍♀️i took a test just to be sure but it was negative but would it have been too early. Everyone ive spoke to said about 6 weeks and it was 6 weeks with my first Lately ive been feeling really ill migraines sickness and heartburn. Im not planning on another baby but ive been trying to rule out everything that could be causing me to feel so ill and have no period idk maybe im just paranoid that something isnt right but im just wondering when everyone else had theirs when formula feeding?
