It depends on the method of delivery. Micronized pills are gone from the body in 3 days I believe, but you feel it much sooner. Injectables are designed to linger for a little bit. Recently I had to wait 2 days longer than normal because they had to special order a vial, and it wasn't too bad, I really think I had a little bit of an excess in my system anyways. But the few times I missed just single a dose when on orals....that wasn't pleasant at all. For the first few months until I was used to injecting I got hot flashes, super angry, shaking, headache, blahs, depression, etc...for a day or two before the next shot. Thankfully that doesn't happen anymore.
Try to stay calm and remember it will all be over soon.
