Brittani • 29.. Married 2012.. Boy mama💙 and another 👶🏼 on the way!

So I posted the day before yesterday about light spotting all day. Yesterday I had none at all, and then this morning it’s back. I spoke to my Ob and they can’t get me in until Tuesday and said to go to the ER if I feel I need to. I’m not cramping and the blood is brown. I haven’t had sex or an exam so it’s not from that. What should I do?
