Your symptoms are not specific for early pregnancy
and they can be premenstrual as well. You have to wait for your period and if you miss it, get a pregnancy test with a fresh early morning sample of urine. The test is done 3-7 after a missed period. If you wish to have an earlier confirmation, you can get a blood test
for serum beta-hCG
measurement. Please review your results with your consultant. Take care.
