first round of letrozole

Tara

in November I did my first round of letrozole I don't know my normal cycle length cuz I have polycystic ovary syndrome cuz I don't have my period or ovulate on my own I did ovulate on the 8th thanks to the letrozole 10 DPO today pregnancy tests are negative when I hit 14 DPO and if my tests are still negative does that mean I'm out this cycle
