Dear Christina,
In science, there is no scope just for any guesswork. If someone supports your guesswork, you just get euphoria and nothing else.
In fact, the first cardinal symptom of
pregnancy is missing a period. All other symptoms like nausea &
vomiting,
frequent urination and breast symptoms appear about a week or more after the missed period. Anyway, discharge, cramping and
tiredness are not the classic cardinal symptoms of pregnancy.
And even if all the cardinal symptoms are present, pregnancy has to be diagnosed by confirmatory tests.
So please wait till you miss your period and a week after that perform pregnancy test on the overnight first morning urine sample. Earlier these tests may report false negative. Alternatively, you may opt for
Beta hCG test which is very sensitive and gives reliable results even few days before missing a period.
I hope this should bring down your panic and help you for scientific approach.
