Do you think I’m pregnant?

I’ve posted a picture of my cycle below so you can see ovulation day and the start of my last period but I started having symptoms this past Wednesday of bloating big time (I am a plus size woman but I definitely felt more bloated than I ever have) and gassy, cramps, backaches, headaches, irritable, leg cramps, and nausea. I started having some spotting that night (which I am assuming was implantation bleeding) and it lasted in and off very very lightly for 3 days and stopped yesterday. I took a test this morning and it was negative. I have been feeling really weird though for the past few days, my whole abdomen area feels sore around to my back, and I have been crying like 5 times a day. I don’t see how I can’t be pregnant, did I test too early? I would just really like to hear your opinions.
