Hello Anna, and welcome. I am Dr. Norm, and I look forward to helping you today.
Longer periods and then prolonged bleeding are generally due either to hormonal changes or to fibroid tumors of the uterus. Since you've had a fairly recent scan which apparently did not show fibroids, that makes it likely that your abnormal bleeding is due to hormonal changes.
The way to know and also resolve the bleeding would be treatment with hormones. A low dose birth control pill taken for a month or two would likely clear up the prolonged bleeding and also cause your regular periods to be much shorter.
Assuming that after 2 months on the pill, your periods were shorter and more normal, that would confirm that hormonal changes have been responsible for the abnormal bleeding. Then you could go off the pill, but you and your doctor could use hormones in the future as needed to control any abnormal bleeding.
In case your bleeding did not normalize on the pill, then the cause could be further searched, possibly with a special ultrasound (sonohysterogram). Best wishes.
Dear Dr Norm,
Thanks so much for your answer.
The scan actually showed one fibroid on the right side of my uterus, but I was told it is very common and nothing to worry about.
I am planning to try to get pregnant later in the new year (after my wedding in August). Would going on the pill for a short period of time have any effect on my chances of getting pregnant? Or would you have any concerns about my wish of getting pregnant next year considering there is some abnormality with my period currently?
