no cramps & it was early?

Hi,
Welcome to ehealthforum,
If you have been sexually active after your last normal periods (and not on any form of birth control measures), then the symptoms of early periods and absent pre-menstrual symptoms could be suggestive of possibility of pregnancy. Sometimes you can have variation of +/- 5-10 days in your usual menstrual cycle due to various causes (which is considered to be within normal limits). If pregnancy is suspected, look out for development of any new symptoms. Wait and watch for your next periods. If you do not get your periods within 10 days of expected period dates, or if you get abnormal periods, or if you develop symptoms suggestive of pregnancy, you should consider visiting your gynecologist for thorough examination (to confirm pregnancy related changes/signs in body) and blood/serum HCG level test (to confirm/rule out pregnancy accurately). Take adequate rest. Drink plenty of water. Maintain healthy diet.
Take care.
