Bleeding bright red

Ok so I've never actually notice when I lost my mucus plug for my first two kids. So I have no idea what it looks like. I'm currently almost 39 wks and the past two days or so I've been experiencing heavy egg white discharges (sorry if it's tmi) which seems like it could be my mucus plug. Then this morning no more discharge. Just now I went to the washroom and I see bright red blood when I wipe. I looked in the toilet bowl and there's little clot like blood. I'm scared. Should I call my midwife or is this normal when you lose your mucus plug? Please help. It's 2 am so I don't want to call if this is normal. Thanks.
