Implantation?? TMI pics!

So I tracked my cycle through this website and it tells me when I possibly had implantation.. it’s like two days off from glow app tho. Being that I had unprotected sex on 8/3/20 twice that day but different times. And had sex last night (8/13/14)....Based on my pictures (TMI) according to this implantation calculator is actually right!! Bcuz I did have light pink spotting and slight red spotting w/ mucus discharge (different times) yesterday. Also was cramping in my lower pelvic area, cramping in lower back, tingly/pulling sensation in my belly button on 8/12/20 and tingly feeling in nipples on and off for like 3 days now. If I am pregnant when do I start testing? As my cycle is 26 days...Could I have been having implantation symptoms?
