11 days late

Lizbeth • I'm rad and gr8 at math

So I’m 11 days late and yesterday I had some blood come out and I thought it was my period and nothing has come out ever since other than that brown stuff which I think is dried blood. Would this be considered spotting or my period? I took a pregnancy test at 5 days late but it came out negative and I haven’t taken one ever since. My boobs have been so sore for the past two weeks. I’m on the pill but for the past two months, I’ve started being inconsistent with them and my boyfriend came inside me over a month ago. Is it time to take another pregnancy test?
