36w3d lost mucus plug

Victoria

So I went in for my OB appt this past Tuesday , they checked my cervix and I was 3cm dilated and 60% effaced . This morning I noticed some brown discharge on my underwear and immediately thought I was losing my mucus plug. How long should it take to go into active labor at this point 😩 I know everyone is different but me and my boyfriend are at a loss😂😂
