You may did rip some of your tissues inside of you...Best bet is to call your professional pirmary dr if you don't like your OB-Gyn...Ppl have been saying that you should start peroid after IUD is removed...I'm getting it removed tmw...Good luck!
Its possible. if concerned call and ask your gyno or regular doctor
I would call the advice nurse. Your cervix was not dilated when you did this, so you could have caused some damage and require further gynecological care. It would be good to schedule an appointment just in case.
