Is this implantation blood?

I’ve felt weird all day. I gagged twice this morning over things that wouldn’t make me gag...I’ve had these weird pains on my right pelvic side and my boobs are sore. I’m suppose to start my period tomorrow but I usually feel it coming on days before and I haven’t. I’ve been exhausted for 4 days now to the point where I can fall asleep at work.
