Late and anxious

Julie • I`m 26 years young. I have an amazing husband, 8year old step son and our almost 3 year old daughter. My family is my❤️
I'm 5 days late and I took a test yesterday but it was negative. When I clicked the I'm late tab on this app it just pushed my period back a couple days. I'm always very regular and the only other time I've been this late was when I was pregnant. I'm feeling very anxious because I don't like not knowing what's going on, especially with my body. I want to take another test but it's like if I start I'm not and if I don't I am, so why waste the money? I just really want to know for sure.. The waiting game just increases my anxiety.
