It took me 10 cycles. TTC absolutely sucks. Best wishes for a quick BFP. Keep strong...you'll definitely get there soon!
In the mean time, make sure to just get a general blood test (including testing your thyroid) to make sure there's no tiny little, easily-solvable problem that's preventing you from getting your BFP. That's what happened to me. Once I figured out what it was, it took me 4 months to correct it, and then BAM...preggo as soon as my blood levels were normal.
Best of luck!
