period was 2wks late and like spotting with no pain?

Hi,
Welcome to ehealthforum,
If you had been sexually active (and not on any regular birth control measures), the spotting in between periods could be suggestive of probable implantation bleeding. The delayed periods, lighter periods, increased tiredness, backache, etc could suggest few symptoms suggestive of pregnancy. Look out for development of any other new symptoms if pregnancy is suspected. If periods have been abnormal, or if the symptoms suggestive of pregnancy are persistent, or if you suspect chances of pregnancy, consider visiting your doctor/gynecologist at the earliest for thorough examination (to confirm pregnancy related changes/signs in body) and blood/serum HCG level test (to confirm/rule out pregnancy accurately). Be in regular monitoring and follow-up with your treating doctor/gynecologist and report any new/abnormal symptoms immediately. Drink plenty of water. Take adequate rest. Maintain healthy diet.
Take care.
