What is this?! Help please!!

Please tell me this is normal or not my mucus plug. I went to the ob yesterday and they found blood in my urine. They didn’t tell me what it was or prescribe me any medications... they checked my fluid and baby’s heartbeat everything was fine but today this popped up in my underwear. I’m 17w6d. It’s more of a gelatin feeling than a creamy/water normal cm
