Tmi pic ,sorry

Rana • Married a year and a half, pregnant with first child.
I had my cervix checked this morning and had a good Amt of red blood when I wiped later but eventually just a little brown and it stopped by this evening. We just had sex and when I went to bathroom this came out. Is this normal? Is it my mucus plug or a blood clot? I have a little cramping
Nothing much. 37+5 now and 1.5 cm
