Implantation bleeding?

This is my chart… it’s to early to test as it says to wait till Friday. I’ve been having light spotting(*******PICTURE UNDER CHART*****) . Like this morning it’s pink and mucas was more red but not like my period, but nothing ever after and now it’s just brown. Not enough for a pad but that’s all I had to wear. I’m cramping, lower back pain, sense of smell increased and just feeling off. Which is also period symptoms. So I wasn’t sure if it was worth testing or just not. No need to be rude. I wasn’t tracking ovulation so I honestly have no idea. With my cervical mucas id say I ovulated the 31st if I had to guess it.

This is all it’s been the last two days…
