usually i get cramps.but this time i dont?

Hi,
Welcome to ehealthforum,
Lighter bleeding during periods, absence of usual menstrual symptoms (like abdominal cramps, back pain, presence of clots/tissues in bleeding) could suggest few of the early symptoms of pregnancy. If you suspect chances of pregnancy, consider visiting your 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). If pregnancy gets ruled out, further evaluation would be needed to look for the underlying cause for your altered periods. Treatment as needed (based on examination and investigations results) would be started to help you get your periods regulated. Consider being 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.
