Late but not pregnant?

My husband had leukemia awhile back and wasn’t supposed to be able to have kids. We were finally able to get pregnant with our first 2.5 years ago (woohoo). We figured this time around would probably take a while too. This month I was 6 days late (which has never happened) and have been having nausea, fatigue, etc the last 1.5 weeks. I took a couple tests the other day and they said positive but then realized they were expired tests. I took a new one today and it is negative. This evening I started spotting a bit.

With our past, you try and not get your hopes up but I am still feeling a little disappointed :(. I guess we will see next month!
