Cervix Check - Plug?

💜

Hi mamas - had my second cervix check today (37+3) and ob said finger tip dilated very soft. He even tried to sweep my membranes but didn’t wanna cause me too much pain (lol).

I went to pee and noticed this, is it beginning of plug or left over gel from the internal? I peed already before this one and nothing came out. Also, it’s tinged pink/peach which I assume is normal/common after a check?
