has anyone ever tested negative after 3 months say and became positive in the next three months from the first exposure?

It's 90 days,you see HIV tests check for antibodies.Antibodies are what your body produces to fight off infection,In the case of HIV it takes your body about 90 days to produce enough antibodies to show up on the test.To be safe test yourself again after 6 months. However it's important to remember during the window period you are highly infectious since you body has not yet built up enough antibodies.So please always use protection.So it is rare but possible.very good question

I was just at the doctors Friday and had an HIV test done and they told me that it takes 3 to 6 months to show up on a test.

10 years is incorrect...I think the answerer is confusing the "window period" with when people start eperiencing symptoms, which varies anyway
the window period is 3 months
around 1% of infected individuals take longer to show detectable antibodies to HIV
from reliable sources, most people seroconvert within 4-6 weeks from exposure, that is, tests can detect the antibodies to HIV
although the window period is actually 13 weeks

Seroconversion is supposed to be three months like you say. People vary. I don't know by how much. Don't forget that tests don't get it right all the time.
The net says:
...sensitivity and specificity of each ELISA kit was ranging between 86-100% and 75-90% respectively...
Sensitivity is how many of the positive people the test can pick out, and specificity is how many of the negative people.

most hiv tests look for antibodies, which take up to 12 weeks to develop, which is why there is an advised 12 week window period. if usure, ask for a viral load to be done. this can be done if hiv is suspected

I don;t think so. The window period IS 3 months, and this itself is probably quite accurate. I don't think it's likely that you;ll sero-convert after 6 months if you have not already sero-converted after 3 months.

Usually 3 months RARELY longer but possible in some people.

3 months is the cut off period, so if you are neg after then you're neg!...;

unfortunately the time period to show + after an exposure can take up to 10 years, it depends on how fast your body reacts to the pathogen.
