My daughter's friend has the same problem. She's also on Yasmin with good results. It does take time to regulate. If you are concerned about the amount of flow you are having (like if you are saturated pads every couple of hours) be asked to be seen while it's happening. Or do what I did (I don't have that condition, but have had other reproductive conditions) just showed up at the gyno's, and let them "see" what was going on (in my case I was having extremely heavy bleeding due to endometriosis, and fibroids.

I'd say definitely give it some time, and if you have concerns at all you can call one of the nurses at your gyno's office.

Best of Luck, Lisa.
