grayish pink spotting? helppp please!

Ashley
Hey ladies! Anyone have any similar experiences or advice? 
I went to urgent care last week for pain in my lower right abdomen, (pretty much my right ovary location) and after blood work and urine tests they were pretty sure that it was a UTI. however, they said that if the pain didn't clear up after the antibiotics then to come back in for a CAT scan. 
Last night during sex I started heavily bleeding bright red, with only minimal cramping in the same spot, and my period was due 8 days later. Today I was only spotting pink when I wiped, and then tonight the pain came back a little and I had watery greyish/pink discharge. Any ideas? Making an appt with my OBGYN as soon as they can get me in but it may still be a week
