Late period

As

My husband and I have been “not trying” for our second baby and my period is 9 days like and still nothing. I took a ClearBlue digital and it came back negative but I’m thinking it may have been too soon. Thinking about going and getting a cheap dollar store test (non digital). Have y’all had any luck with those? Any I should avoid? Should I trust the clearBlue digital? I’m a little sad and ready for our next little one.
