My Sister is 40 years old. Weight 59kg. From last 2 months she is getting frequent periods. She is getting normal period approx. 26 to 28 days cycle but in between that at 9th or 10th day she is getting bleeding, that lasts for half day or 1day. Bleeding also very minimum. She is taking Banetowa 8 daily for bp. Her bp normal (72/115). Blood Sugar 110 pp. She does not have any other problem. What needs to do? Previously approx. 9 months before she got one time UTI, that time USG and pap smear test did, both tests results were normal. Here I am attaching the USG report. What needs to do?
