Need some help!

Shalee
I'm 25 and have been married for 2 1/2 yrs with a 21 month old daughter...been ttc for about 2 months now n no luck...my period is due either 2moro or wed...have been very bloated, nauseous, tired, crampy, and moody...taken a few test and they were all BFN...I'm very down in the dumps since I want this so bad..should I take another test or wait til I miss my period?
