I've been ttc for 3 months now, this month I'm a week late. Took home pregnancy test 2 days ago got negative. I went clinic and they got me a test it was also negative, my nurse told me to come back next week. It's kind of frustrating me to wait that long. So, could I be pregnant and get negative tests ? Or could it be something else? I had some symptoms, like tender breast, nauseous & late erupt.
