Hi,
Welcome to ehealthforum,
Progressively lighter and shorter periods, spotting, appearance of blue veins over breasts, breast tenderness, stretch marks on breasts, abdominal cramps could suggest chances of pregnancy. Other causes for alteration in period pattern could include hormonal changes, thyroid abnormalities, endometrial problems etc. If pregnancy is suspected, look out for development of any other new symptoms suggestive of pregnancy and consider visiting your gynecologist/obstetrician 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, go ahead with getting further evaluation done to look for the underlying cause or your altered periods. Treatment as needed (based on examination and investigations results) would be started to help you get your periods and regulate them. Be in regular monitoring and follow-up with your treating doctor/gynecologist and report any new/abnormal symptoms immediately. Take adequate rest. Drink plenty of water. Maintain healthy diet and lifestyle.
Take care.
