All the symptoms that you mention are not specific for pregnancy
You have not mentioned the date of your last menstrual periods.
If you have skipped your period, and taken the tests which are negative, then it means you are most probably not pregnant.
If you are not yet overdue, then it is too early to read into the tests.
Repeat them once you mis your periods.

If you do not wish to get pregnant, then use regular contraception
All the best.
