Help!!!!

So, I went to the bathroom early this morning, when I wiped, I seen this, (first picture), haven't seen any blood since. I'm cramping, having headaches, nausea, sore breasts, and bad back pain, well, in the second picture, I logged unprotected sex on April 20th. I had my period on the 30th, it was extremely light. My periods are also very normal, in the 3rd picture, today's the 21st, I'm supposed to start my period in 7 days, my periods have always been regular, so idk what's going on. Can someone help me??
