patience is a virtue????

I am 28 and my husband and I have just begun TTC this cycle and am so overwhelmed with with excitement but also scared to death that it might not work. My husband and I had sex every other day during my ovulation.  I also happened to have my routine ob/gyn appointment that week and my doctor told me my cervical mucus was exactly right for conception. Naturally I went right home and celebrated with my hubby :)! A couple of days later I had a pretty bad headache that lasted off and on for about 2 days and I felt like I had been run over by a bus. I have continued to feel exhausted but no more headaches. I have had cramping off and on but no spotting so far. Now is the worst part because I am not due for my period until dec 6 and I am dying with anxiety!! I'm sure this is all in my head but I really feel like I might be pregnant. I need some support while I wait because it's all I can think about....when do I test????
