Jodeci • Thu, Oct 20

So im 16weeks 2 days pregnant with a Low Risk baby girl.. Today when i wipe started spotting Dark Brown Discharge. I feel completely normal, no cramping or anything. Just a really bad cold. I have my 16week OB Appt tomorrow and ive checked baby girls heartbeat which was in the high 140s. Do you think i should go in tonight? Picture is attached.
