Halp! Hair fall out.

So I just recently gotten my birth control taken out. I had Nexplanon for a little over 4 years. I read that birth control can make your hair thin/fall out. I havnt done anything weird or extreme to my diet. I do eat more protein, drink plenty of water and i wash my hair like once or twicr a week to slow my hair from falling out. Im getting very anxious about it because my hair used to be very thick, plus ive been trying it grow it out from a previous bob..any suggestions to help it grow back strong/fast. Should i could it to a pixie or bob again..it is currently as long as my bra strap in the back.
