Should I start celebrating?

I was expecting my period yesterday 01/09/16 or today 01/10/16. My husband and I have been trying to conceive a child for the last few months. I have taken 7 tests in 4 days, all of which indicate pregnant. Is it possible to have 7 false positives in 4 days? Sounds like a dumb question lol, but this is all new to me and I don't have an idea how this works. Should I start celebrating?
