Reaching the end of my rope!!

Susi
I have a dilemma, my period was supposed to come 2 days ago and still nothing. I have taken 2 clear blue plus tests and they both came out negative. I have no period symptoms, but I have on and off nausea, dizziness, heart burn, I'm really tired all the time, I can't sleep at night, and according to my husband I'm more moody than usual. Not sure what's going on. I called my gyn and they said that of i havent started af or gotten a positive result by monday then to let them know. I'm so irratated at the situation and just ready to know if we are expecting our 2nd child.
