I was wondering if I could get some advise. Have any of you ladies done letrozole, gotten to the end of your cycle and had a lot of pregnancy symptoms but tested negative and been pregnant? I am 5 days from AF and my breasts or very sore, nauseated off and on, can't sleep all night eith out waking to go pee and just a general sense that I am pregnant. I've tested with the walmart .88 cent tests but nothing. Not even a faint positive. Any advice? I know I'm not out till AF comes, these symptoms are unusual for me, but this is the first month fertility drugs have worked and gotten me to ovulate so idk what to expect.
