Very odd period..should I test?

Hello! The last three weeks I've been experiencing lots of things. A few being abrupt and sudden blurred vision, nausea, dizziness. I was pretty sure I was pregnant. Then, I started what I assumed was a period. It is over after less than 36 hours. The blood also was not clotted or lumpy. It was very liquidy and much different than my normal periods. Do you think I should test for pregnancy??
