Discharge, I need help!

Is this my period coming or is this implantation bleeding? I had this yesterday, but it was super super light pink but today it’s more red. I’m really not familiar with implantation bleeding but it’s the only other option that can be. I had sex on April 13 so it’s been about two weeks. I’m supposed to get my period on May 3, what could this be? I’ve been feeling slightly nauseas, and I’ve had these cramps in my lower stomach. Every time I get these cramps I have to go to the restroom! My poop has been strange and I’m not sure if there’s something else wrong with me! I’ve also been getting this pinch feeling pain on the right side of my stomach, I’m not sure if this is my ovaries? Please help I need anyone that can give me any info.
