Hello dear,
I understand your concern.
In my opinion as the pregnancy test is negative there might be no chance of pregnancy.
Usually the urine pregnancy test gives accurate results a week after missed period.
So incase if the test was done early i suggest you to repeat the test.
If the repeat test is also negative there is no chance for pregnancy.
If the
vaginal itching is associated with white curdy discharge then it suggests
candidiasis.
Pain during urination needs to rule out any urine infection.
Avoid stress as stress also cause hormonal imbalance leading to delayed period.
So relax.
Take adequate fluids upto 3 litres per day to prevent
urinary tract infection.
Sore breasts can also be seen during premenstrual phase.
I suggest you to
consult doctor to rule out any
vaginal infection.
Nothing to worry as such.
The pregnancy chances are rare.
Hope this helps.
Best regards...Dr.Srilatha
