so this happened today....

So I noticed I was 3 days late today and decided to take a test this is the same test. But what I'm confused about is Tuesday I went to the er And they took a test and I could hear them talking after I took a test there; they were saying Ima say thats a negative. So they took me to do X-rays and I'm on pain meds cause I broke my tailbone. So now I'm hoping that the X-rays and pain meds are gonna hurt anything
