Hi, so I'm a little nervous and worried. My period is 13 days late and I am 46 days into my cycle. My breasts are a little tender but the have occasional sharp stabbing pains. I also cannot stand the smell of pizza which is my favorite food. Am I pregnant? I took 3 pregnancy tests which all said negative. So, in that case, should I go to the doctor?

It is almost time to test, you should not START testing till about 14 days late.
And even then some women do not test correctly even till 2nd or 3rd month late.

Also, are you testing with first urine of the morning, as soon as you wake up ?
