Could I be pregnant

Tiona

Me and my husband are trying to have a baby. I have a 1yr old (2yr in March) and we have been trying for a year. I recently spotted from the 10th-12th. My period was due on the 13th-17th. I've had no symptoms except for a lot of gas. I'm scared to test cause I don't want it to say negative. What should I do.
