Sounds like too much oestrogen - the lining has built up to much!! Keep using the Utrogestan for the full 14 days and I would then take a break from the oestrogen for 4-8 weeks to see what happens - this is basically a re-boot. If you are peri meno then problematic bleeding is more likely, especially when using Utrogestan as it isn't as strong as the synthetic progesterones. Dg x
