Am I pregnant??

So, me and my boyfriend had unprotected sex last week, 28th & 30th of January and then 1st of February. My period is due the 8th of February. Since then, ive had slight pain in my right side like next to my vagina, i think its where the ovaries are but ive never had it before. I’ve felt extremely hot and dizzy and it sounds strange but a feeling like im being strangled if things are too close to my neck. Ive also had a yellowy discharge that ive never had before. I googled it and implantation bleeding came up. My picture is the zoomed in one, a picture of implantation bleeding is the one where you can see the persons fingers and shoes. Are they the same? Whats the chances im pregnant?
