Fertilitea

Anyone had a longer cycle and negative hpt while drinking fertilitea. My cycle was 32 - 34 days since starting the tea this month I'm currently on cycle day 40 and still no AF!! Had all the Cramping prior to the cycle days 32 and 34 which would be my normal time of the month and still slight Cramping at 40 days now. If you did try fertilitea and had an extra long cycle how long did u af show if you got a Bfn. So confused wish I had not of drank the tea now so frustrated I really can't say how much I wish my Af would show up where as normally I have fingers crossed it dont. Help please.
