Am I pregnant??

So me and my boyfriend had unprotected sex on the 28th & 30th of January and then again on the 1st. Since then, ive felt so hot and had pain in my right side next to my vagina, ive felt dizzy too. Ive had some unusual yellowy discharge and when i googled it came up with implantation. My period is due in a couple days. Am i likely to be pregnant? Are the pictures similar? My picture is the zoomed in one, the implantation bleeding is the one where you can see the persons fingers and shoes. Helpp!!!
