My last normal period was in February, after I didn't get my period in March and got it April 12th but it was very light and spotty and with many little clots. Then I got it again a week and a half later on April 30th and it was again the same very light flow, spotty it almost looked brownish and once again a week I have it on May 15th with the same spotty brownish discharge. My breasts have been tender since April 12th. I have ruled out pregnancy because I have not been sexually active within that time period. I also experience light cramps when the period begins. Each one has lasted on average about 5 days. Within a month's time I've had my period 3 times. I am concerned.
Any advice would be great. Thank you.
