Period Issues

Ashley
This month my period was extremely weird. I had cramps the day i thought i was getting my period but it went away in minutes. I felt like it was coming out and when i felt that i needed to change my pad. It would be clean, only like a line littertly of blood would be there. But when i wiped it was bloody but not the pad and that happened the next to dats and then when i wiped on the third day it was over. Im a nuts or like what can this possible be. I mean yeah i have sex but i use condoms but my "s/o" would have noticed if it ripped right? Should i see a doctor?
