TMI pictures but please help!!

Today I'm 7pdo, around about 4dpo I started getting what felt like period pain cramps, so I just though it was AF coming, but then I started getting headaches which I NEVER get, I'm feeling sick, but not being sick, and I'm not a sicky person either... I'm having side pain and there's a niggling feeling in my ovaries but my right ovary today was giving me real bad shooting pains up to my boobs. When I'm normally near a AF I just have the pain, not all this! I've also got  sore boobs, which is a first for me ever. I don't want to get my hopes up but I don't know if this is it, or just AF playing up... I tested today but BFN, I know it's too early but I couldn't help myself.. This is the CM I've been getting since 4dpo, it was thick.. Now watery. Anyone got an opinion on this? I need some advice! X​​
