Ttc advise

I have a 35 day cycle, period due today, but hasn't come. One week before period I was bloated with mild cramps and backache for days. 2 days before my period was due, most symptoms subsided. We have beenTTC #3 since September, and i just thought it would happen sooner, as the other 2 were conceived so easily. I check my cervical position and mucus and chart daily. Took an early test yesterday, BFN. I took one this morning, NO LINES SHOW UP!

I guess I am just looking for advice on any of this.
