Spotting all day. 35 weeks and 4 days.

Went into l&d yesterday and was considered being in my first stages of labor... Was 1 cm and 80% effaced. I've been spotting since lunch time today. Almost 6 hours. Only see it when I wipe to pee. Went from clear with brown/red spots to light pink with brown/red spots. I've had BH contractions nothing painful like yesterday's and not regular/consistent.
