I have taken Utovlan for 10 days to bring on a withdrawal bleed (no periods for 11 months due to PCOS ). How long after taking the last day of tablets should i expect the bleed to start? it has been 2 days and nothing. I had a lot of side effects when i was taking the tablets - uterus pain, stabbing ovary pains, sickness, diarrhea, nausea and imsomnia if that makes a difference? thank you
