Missed period but old brown blood help!!!

So last Tuesday (1-16-18) I was suppose to get my period. It did not come. But 2 days after the missed period I started discharging Brown (Looks like the last day of your period). Just spotting nothing more. I did take a pregnancy test came back negative. It’s been like this off and on this past week.

So today I went to the bathroom nothing on my undies but when I wiped it looked like a glob of bark blood. so I thought my period started. I went back to the bathroom like 3 hours later and all that was on my pad was 2 tiny dark brown spots. When I wiped there was some brown discharge after wiping four times absolutely nothing on the toilet paper. Then, I went back to the bathroom again (2 hours later) and nothing on the new pad but when I wiped there was brown discharge on the toilet paper.

i’m not feeling any sort of pain I don’t have any sort of sign that my period is about to come either. I’m 33 years old I have two children.

Just lost my job so I don’t have insurance at this moment but I’m waiting for my application go through the state So once I get insurance I will go see a doctor but for now I just want to know if any other woman has gone through this.
