Lost mucus plug day after membrane sweep

I’m 37w4days pregnant. Yesterday at noon I got my membranes swept (getting induced Monday medically is the only reason I got a sweep done this early). This is my third baby & all my sweeps have been unsuccessful w my previous 2 kids. But since yesterday I’ve been seeing brown stuff when wiping and just a little bit ago wiped and lost a big portion of my mucus plug which was brown as well. Haven’t had much contractions though since yesterday, just very infrequent ones. Should I hold out hope that it’ll maybe happen tonight (bc after 48 hours it’s more than likely unsuccessful) or not think anything of it as losing plug isn’t a forsure sign of anything? Woke up with a headache & baby was way less active this morning and last night than he usually is but has been moving around a lot again the past couple hours. That’s really the only difference I’ve noticed since getting the sweep. Not sure if I’m effaced, they haven’t said but have been told I’m very soft. Last week at my apt I was 1cm dilated and yesterday I was 2cm
