Like with any other birth control pill,
Lutera Birth Control, can also cause clots
in any part of the body. If this happens in lungs, then this can cause progressive breathlessness and can be dangerous. You must get a CT scan of chest immediately.
Other than that, the pill also causes bloating of abdomen. This can also cause breathlessness.
I suggest you first go to ER to rule out clots in lungs. Do not want to scare you.
