What do you think?

So I’m 12dpo with a 16 luteal phase. My breast have been really tender and heavy for days now. I had a metallic taste in my mouth all day 8dpo and 9dpo. I started cramping and having some twinges yesterday at 11dpo (evening). Today I’m queasy. I took an hpt test this evening (not FMU) and it was a BFN. I also took an ovulation test just cause i had them and i have attached the pictures. I know it’s always two lines but that one is a bit darker than normal. I also know that typically you can have a surge right before your period but again my period isn’t due for 4days. What are your thoughts?
