Pregnant maybe?

As

Soooo my boyfriend and I have been together on and off for 2 years now. He has a daughter from a relationship before me. We are happy together just have been going thru a lot trying to grow up but also be together. He is 18 and I’m about to be 18. I have been going thru some stress with my family and then with his as well. Plus him and I bicker back and forth. I know I have been under tons of stress and I’m now 6 days late on my period. I’m scared Bc I could be pregnant and I’m so young still. We both want a baby but the idea of actually being pregnant is scary. I have a pregnancy test to take I’m just really scared to find out if I really am pregnant. I don’t know what to do.
