Number of pregnancies and Mirena IUD?

Can the number of children one has given birth to effect the intensity of headache experienced with the insertion of Mirena IUD?
I've have three children and the discomfort was minimal, but a relative with 2 children experienced excruciating agony.Number of pregnancies and Mirena IUD?
I would think that it would depend on your cervix. If you own had children formerly and if it was lately you delivered consequently your cervix would be different later someone's who had never have children before. Probably have to do with one's agony tolerance.
I've only have 1 child and I didn't experience any pain, so the answer would be no. I ruminate it has to do next to a tolerance for pain.
I get the mirena iud put in a year ago I never have any children they put me on it because I had high-ranking blood pressure. From what I got from my doc be the more children you had the easier it be because me not having any kids I be in anguish!! blood pressure droped and almost passed out. So you should be okay.
