Its not dangerous but over a period of a week (which is what Doctors calculate the dosage,) you are going to be 200mcg short so obviously your levels are going to head towards Hypo.
Often if a person goes Hyper too fast on meds, a Doctor will tell you to stop taking the meds for a few days to get the Free T's back down within range and the TSH up.
I would be getting your levels checked and take it from there.
Just make sure you dont forget too often or you are not going to feel too good approx 2-3 weeks later.
Good Luck
