Pregnant?

So my husband and I have decided that we want to TTC ... I was on the depo shot for about 8 months I finally got off it August 30th and my period is 20 days late. I've taken AHPT about 2 weeks ago but they've all came back negative, I also had a blood test done also about 2 weeks ago and also came back negative.. but I've had many symptoms such as, dizziness, nausea, itchy boobs, and ive been very emotional.... thoughts? Should I be hopeful?
Update: should probably have mentioned we have sex everyday.. sometimes 3 times a day and I just ovulated. I'm just worried that maybe I took the test too soon?
