Could I Be Pregnant?

Summer • Hi I`m Summer. 19 years old. I`m married for a year now. Trying for baby number one.
Okay, well last month I was a week late on having my period and then I started but it lasted for only 2 days. It's time for me to start again this month and I haven't yet. It's a couple days late. Could I Be Pregnant??
