Help?!! False positive?

I've taken 2 pregnancy tests. One yesterday, one today. Both were very strong positives, wooohooo!! I'm 4 days late, sore breasts and cramps primarily for the last week. I've scheduled a doctor's appointment but I can't be seen until November 5th. I'm so afraid to believe these tests only to find out it was a fluke. Is it possible to get 2 false positives?
