(Possible TMI) I had a very heavy period a week ago and lost a lot a blood in large clots. I woke up in the middle of the night feeling VERY weak and dizzy and like I was going to pass out. I had used Progest-E when the clots started, thinking I might be able to stop them. The bleeding has stopped, but I am still waking in the night with a bad headache that won't go away. Also I am still feeling light headed and dizzy at times. Any suggestions for this headache and dizziness?
