Anyone else have this happen?

Jessica

As of today I am 9 days late for my period. I took a test at 4 days and just took a test this morning both came back negative. Could I still be pregnant? Anyone else have this happen and didn't show a BFP until later? Just yesterday my boobs started getting sore and Feeling super tired. Just looking for some advice or help. I don't wanna drive myself crazy. Because hubby and I have been trying for a while.
