I have been experiencing extreme fatigue, nausea, and vomiting for the past couple of weeks. I took several pregnancy tests at home. Two were very faintly positive the last was negative. Could I be pregnant?

First question... are you even late for your period... and if so how late.

Are you at least two weeks late? If not wait until you are... if you are, exactly WHEN are you taking the tests?

Also those are all symptoms of something else... GUYS get them frequently too...

I guess I will assume you are having sex ?
I will have to assume you are late from period??
Since you would not be having those signs unless late.

Also tests showed positive, that was a few minute after test ? Because if you let them lay, they will often turn that way.

Are you at least two week late from period ? You need to be, to properly test
Are you using first urine of the morning ?
