Freaking out!

Sarah • Hi my name is Sarah, I'm 22 years old and I've been married for a year and I am newly pregnant 😘❤️

Okay you guys I'm freaking out a little bit! I'm late on my period and I'm NEVER late, I'm always right on time every single month. I took a test last night and it said negative but then I tried to take one this morning and it was an error and didn't say negative or positive. What should I do?? Should I buy more tests or call my doctor?
