FRER so I don't know...when I went through IVF I got a faint positive 7dp6dt which is about 13 dpo. I honestly feel like AF is coming though so I don't want to get my hopes up. I won't test anymore, just wait til AF comes. I read somewhere that you can also get an LH surge right before AF comes, not sure if that is true or not but I read it on one of the many sites I've looked at.
