Yellow discharge at 30w 2d ?!

Hey guys!

Sorry if this is TMI but I would hate to call the doc for nothing.

Ive been having yellow discharge since yesterday. Its like a creamy stain on my liner/pad. I don’t think its the mucus plug because it doesn’t look like snot. Also, I change my pad/liner regularly. This discharge is odorless. Im not in pain, itchy or nothing. I just simply had a change in discharge. Im a first time mom so im kinda weirded out.

At first I thought hmmm maybe its pee but its not lol
