Hey friends. First time poster here. Well I am on CD 9 after starting letrozole with a no bleed. Took 7.5 my CD 3-7 and now I am cramping with brown spotting. Boo! What really sucks is my RE is out of town for two weeks and I dont know what to do. I have left several messages with the office and no return. Is this normal? Is it my period? If it is my period, do I take the letrozole again starting day 3? Aahh freaking out!
