AF MIA

Chelcie
Lately AF had been somewhat regular.  This month after my hubby and I were actually really TTC she's a no show.  I tested last Saturday, 2 days after AF should of showed, and got a BFN.  I don't know if it's just me or not, but from after I supposedly ovulated, been kinda crampy and having a heavy feeling in my pelvic area, sore girls off and on. Don't know what is going on.  Should I test again? It really makes me nervous to test, not because of the fact that it might be positive, but because it may be negative again.  I get sad when it show negative.  Hopefully one day it will be a BFP.  I have my annual exam with my gyno at the end of the month.  Any ideas of what I should do?
