Is this my mucus plug?

I am 35 weeks and 3 days. I went to the bathroom and this came out when I wiped. I have had constant discharge this entire pregnancy- but it's never been this much! Could this be my mucus plug? I've asked friends and they said it looks very similar to how theirs did with their pregnancies. I know that they vary from person to person in color, etc. just wanting to get a broad idea to make myself feel better.

I'm a first time mom, and naturally nervous. Also, when you lost yours, how long was it before you delivered. Any info appreciated. Thanks in advance 😊
