Blood conditions and the pill

Morgan

Okay so until about 4/5 months ago, my periods used to be 2/3 days long, super light and with no pains at all and now theyre the full 6/7 days, super heavy and with pains so bad i cant walk so my mum has started talking about going on the pill, my only issue is that i have a protein S deficiency so i cant go on the pill but after a very quick Google search, the copper IUD and the progestin only pill are an option..

My question is whether there is any other options and how effective are those two options? Ty x
