Should I get a test?

My period was supposed to come on Tuesday, today is now Monday. But I was bleeding a bit Thursday and it stopped then again Friday and it was over by Saturday and now I haven’t bled since. My period is usually on time or early. I take birth control pills but I admit I missed them 4 days in a row and then I took them all at once. My period has not yet to be seen ! When I was bleeding it wasn’t period blood it was a dark brown blood and it was on and off until Friday. That lasted literally one day and it hasn’t happened since. 1 day period ? Should I go get a test? I got one but I’m pretty sure it was too early . My period is now 6 days late. What should I do?
