Cervical check

I had my second cervical check today to see how dilated and effaced I am. I have been 1cm and 50% effaced, baby head down for a week now. I didn’t have any fluid leak out last time but this time when I went to the bathroom, I noticed clear fluid on my pad. Is it normal to leak a little fluid with a cervical check? I’m 37 wk, 3 days with my first baby and could potentially go into labor anytime.
