something very similar to this happened to me with the depo shot. i would honestly when you can see your doctor next have them look into a hormone imbalance like estrogen and things like that and also test you for hypothyroidism. until you can get into your doctor the best thing i can recommend is try to stay as stress free as possible and try to get back on a daily routine. i know it will be difficult at first, but it will be worth it in the end. i hope you feel better and find out whats wrong.
The boost in estrogen with these prowerful birth control products now out for the public can cause a long surge in estrogen robbing the body of progesterone to keep your body balanced.
You need a complete panel of gender sex blood labs or better yet - saliva panel testing, along with liver tests to determine what to do to put your body back to normal cycle.
I suggest not doing the BC at all either.
