I am over 2 weeks late for my period and have been tired, and have been constipated. I have taken 4 pregnancy tests since I have missed my period. And they have all been negative. I am also losing my job so I don't know if its just stress or not. My husband and I have been trying to have another kid. So could I be pregnant?

Yes, it is very possible that you are pregnant. But like you said, you are under stress. You have two options I would suggest, One, go talk to your doctor and tell him how you are feeling, they can do a test and tell you 100% for sure and the other is to wait a couple weeks and try another home test.

Good luck
