Period began - stopped - came back

Hello my womanhood (period) started on Feb 5th and ended on the 9th. However on the 7th l did not have a period all day. I thought it was over so nothing phased me, then it came back for about 2 days (the first day back was like a "regular light flow" then the 9th it was light pink almost no tint). I thought this was odd for me because it has never happened before I do not know what it may mean. I also am very stressed from school etc. but I'm usually ALWAYS stressed so idk why that would be a trigger now? Any explanations? Should I get checked?
