Thanks for the query to H.C.M. Forum.
The right ovary was removed , so now there is no need to bother about that.
was benign , so no chances in left ovary but routine check up is necessary.
You have not mentioned the age , which is very crucial for period abnormalities.
If age is around 40 years consider about premenopausal syndrome.
If age is less than 30 years ,than consult a gynaecologist and his opinion will matter in this case.
Hope I have answered your question.
If further any question I will help.
