Is it possible that after 2 months of stopping the contraceptive pill I have irregular periods again?

I used Vines for 8 months, I stopped taking pills in March, also April and May I had regular menstruation, without major pain, but now menstruation has not come, and the test performed on the day of the expected menstruation and two days later is negative. It pulls me in the lower abdomen, and I have a gynecologist only in 3 weeks. Could it be that the irregular ones that lasted so a year before I switched to contraception will come back again? I also had a cyst on my ovary.
