"Hello .. I have a question regarding if im pregnant ive taken 3 tests all negative I havent had a period since nov.4-11th.. then on the 13 of that month I had a spotting of 2days its December 20th now n still no period.."

You either are just skipping a month, are off schedule, or are pregnant - those are the most common reasons.
We don't know if you tested too soon or not.
The holidays can throw periods off.
Too soon to know! If you have sex, you can get pregnant. Each kind of BC has it's own chances of failure. You don't even tell us if you use any.

If you haven't taken a pregnancy test recently, try another one, or see your doctor for a test there. There can be other reasons for not having a period, but if you are sexually active and of childbearing age, pregnancy will be one of the first considerations. If not pregnant, your doctor can discuss other possible reasons for a change in your cycles.

The best time to test, is when you are 14 days late, I do not believe you are at late yet??

But be sure you are testing with first urine of morning, as soon as you wake up
