Am i pregnant???

Me and my boyfriend had sex three times unprotected last week 28th, 30th of January and 1st of Feb. Whats the chances im pregnant? Ive had slight pain in my right side, feeling really hot and feeling like im being strangled, and ive had this discharge thats yellowy, i googled it and a similar picture of implantation bleeding came up however there’s no blood in mine. Im expected on my period on the 6th February, tomorrow!! HELPPPP?? Btw, the zoomed in picture is mine xx
