We did an at home IUI without medical supervision or advice of any kind. I do not recommend doing this unless you know what you're doing!
Our frozen sperm shipment came with a needleless syringe and a plastic catheter. We figured putting the catheter in as far as we could would help our chances, and hey, it was washed sperm anyway and that's all that matters, right?
About 2 days after the 2nd insemination, I started feeling extremely bloated, and had lots of pain and cramping. It felt kind of like when you have a bladder infection, but there was no burning urination. Standing up straight was painful.
I went to the dr to get checked out but they didn't find anything concrete wrong with me. I didn't have a fever, so there was no infection, but I'm pretty sure we irritated something in there.
Whether we scratched something inside, or introduced germs, or I just plain got irritated by the sperm, I don't know. But it was kind of scary, and very uncomfortable.
This is not to say that everyone's experience will be like mine! We didn't take sterile precautions, and I'm sure if we decide to try again we'll study more carefully. I think from now on we'll stick to the ICI and leave it at that!
