Hello, Your symptoms could mean either you can expect a period at any time now or have a very early pregnancy. Please wait for your period to set in and if you miss it, go for a HPT 3-7 days later with a fresh early morning sample of urine. If you wish for an earlier and better confirmation, please go for the estimation of the serum beta-hCG titres followed by a trans-vaginal sonogram to know the status of the pelvic organs. Hope you find this information useful. Take care.
