Did they mention anything like that would happen? I would call and see if you should go in. Just to make sure.
I agree you should call your doctor, have them do some blood tests and Pap smear and also an ultrasound to see is the fibroids may be causing these symptoms. I also have fibroids and I have very long periods because of that. I pass small clots every cycle towards the ends of my periods; I assume is from the fibroid. I will be having a myomectomy next month to have the fibroid taken out and still preserve fertility. Good luck to you'
Hopeful k
