Mirena IUD help!

Lorena • Momma to 3 beautiful babies!🤍🤍🤍
My gynecologist won't get me my IUD becuase she wants me too be on my period, these last two months i got my period friday afternoon and by monday morning i was clear. I called her this monday and i asked her if i could go in and she said she needs me to be on my period which is impossible for me to take control of and my SIL just told me her doctor will get her hers even if she's not on ger period. So now im thinking of switching doctors! I have an 8 month old and i cant afford to get pregnant again, we are still using protection but its still scary!! Lol
