1st Cycle taking Letrozole

Valerie • TTC again. Mom to one 👼🏽

Hello this is my first cycle on Letrozole. I did 7.5. I tested at 10 dpo and was negative. I haven’t tested since. Today I’m 13 dpo and 2 days late for my period. I have not tested. I’m scared because I hear Letrozole makes your period late an I don’t want to be disappointed. Should I just test
