Not trying to get my hopes up!

So tomorrow will be 2 days that I'm late. I took a test 2 days ago and the test was defective. I took another test the next morning and it said negative. I don't have many symptoms (only backache, dizziness, nausea not very often, and my boobs have been hurting) but I also don't feel like I'm going to get AF. I also have been getting AF on time the past few months but this month is different.
