In the current situation, would it be wise to change Sylvie 20 to Sylva 30 without the advice of a gynecologist?

Hi I have been using Sylvie 20 as hormonal contraception and prevention of painful menstruation for two months now. Unfortunately, in the last month there was severe "menstrual" pain (ovarian pain as during menstruation) In the current month, such pains also happen, in addition, I got a slight bleeding about 10 days, which lasts until now, that is, 1 day with a 7-day break between blisters. In the current situation, will it be wise to change Sylvie 20 to Sylvie 30? Since teleporada with a gynecologist is impossible in the near future, I am looking for information here.
