Light pink spotting HELP.

Amanda

LADIES! PLEASE HELP ME.

I got my period twice last month. One for 6 days which is normal for me and then one 2 weeks later for 4 days. Then last night I had pink discharge there was kind of a lot. Then about an hour later it was purplish brown and I haven't seen it since. Should I see a doctor? Has anybody else ever had this? My periods have always been regular.
