Waking up, removing a shrimp tail stuck to my nose, getting up to make some tea, noticing blood dripping on the floor.
The few seconds spent waiting whether or not the blood will stop were not fun. It did stop, or at least slow.
They do warn you about bleeding after inserting a IUD, but they never say how much and how long is normal. Called the medical advice hotline, they told me to visit a doctor on Monday if I don't get better, or immediately if I get worse.
