Hello,

Welcome to ehealthforum

It is very difficult to comment without examining you and USG scan would be the best to rule out whether you are pregnant or not.You can also get a Blood test done to rule out pregnancy.Even an ovarian cyst can be detected by USG scan.
Consider getting the investigations soon and visit a Gynaecologist for evaluation.

Take Care!

Hi,
Welcome to ehealthforum,
If you are having symptoms suggestive of pregnancy, then it is likely that you are pregnant. Urine pregnancy tests can also show you false negative results during early pregnancy days. Blood HCG level estimation is accurate and can detect pregnancy accurately earlier than urine pregnancy tests (at about 11 days post conception). Sometimes you can continue to have period like bleeding at your expected period time during first few months of pregnancy (also known as decidual bleeding). If you suspect to be pregnant or are having symptoms suggestive of early pregnancy, then you should consider visiting your doctor/gynecologist for a thorough examination (to confirm pregnancy related changes/signs in body) and blood/serum HCG level test (to confirm/rule out pregnancy accurately). The levels of the hormone will also give the indication to probable gestational age. Ultrasound scan done would be confirmatory for gestational age and to rule out any other problems.
Take care.
