Mucus plus/bloody show tmi*

I’m currently 37w6d and I’ve been losing my mucus plug since Monday of this week. Today it was brown in the morning and now it’s bloody. I never had a “show” with my first baby so I’m just wondering if this is what it is. I also had my membranes swept on Monday and I’ve been contracting (not painfully) since then. Is my babe coming soon or what?
