All of a sudden it stopped?

I'm 35w4d and I've had discharge throughout my entire pregnancy to the point where I wear liners so I don't ruin my underwear. I've lost a couple pieces of what I assume to be my mucus plug last week but it was barely a dimes worth combined. Today, however, my liner is completely clean as in absolutely no discharge. I would assume if something was happening soon I would have more but there is nothing today. I find it so weird considering the past 8 months it's been the complete opposite ha any insight would be helpful!
