8dpo pain

Sara
This is my first IUI. I have been struggling with the pain. My friend told me she had pain on her first two days and thats it (unfortunately she got bfn). I wake up in the middle of the night because of my pain on my lower back and abdominal. Waiting for a whole week is challenging and i don't know when i am going to give up and test. Q: were you in pain the whole time?
 Q: how soon can i test?
