Am I pregnant I do not know?

I am 31 and happily married I have had two previous miscarriages one was 8 years ago the other almost two years ago. My periods are very regular I have been having my period for over 15 years. I can almost pinpoint the time i am going to start. The date of last period was may 10th and I was supposed to start on the 4th of june. had on the 4th then I spotted once when i wiped on the 5th. I have taken 2 preg test and both neg. I am feeling very tired my are sore sometimes and i have been nauseous. I have had some cramping but nothing bad. I have not been stressed out and no sudden weight loss or gain i do have a sinus cold right now. I am not sure if it is just to early to tell or if i am just not going to get my period. Has this happened to anyone else?
