Thanks for the query.
Most of your symptoms are non-specific and can be seen in many conditions like premenstrual phase, infections etc.
So you better wait till your expected date of periods and if you miss the date, then go for pregnancy
If possible you can prefer blood test
for pregnancy which will give more accurate results compared with urine test.
If test comes negative, you better consult gynecologist and take treatment to regularize your cycles and for ovulation induction
, which can possibly help in getting pregnancy.
