I have line eyes soooo bad! think this is the start of something or am I just being crazy?

I know I should wait a few more days to test (I'm only 10 DPO) but I got all excited because I'm pretty sure I had implantation bleeding/cramping a few days ago. Also I have been super dizzy, kind of nauseous, and feel exhausted (what led me to test last time). Could just be AF though, as she's been a little crazy since my chemical in October.
