questions

I have an abnormal cycle. So my periods last between 7-10 days. Last month my cycle started on May 25th. It didn't end until June 3rd. The last 3 days it was very light like really a pinkish color. Since then I have had this same pinkish discharge like on June 5,6 and 7. And now again since yesterday. I'm extremely nervous about taking a pregnancy test. Can anyone give any insight on what this means?
