WTD, I can only give you my own personal experience and it may be very different for others but I found that I needed very high doses of oestrogen to get any benefit when I had a Mirena coil and even the 100mcg patch was not enough. With hindsight, I wish I had tried using Oestrogel with the Mirena because I have far better absorption rates with it - I could never get anything like enough oestrogen from patches and this was confirmed with blood tests. The problem for me was the synthetic progesterone in the coil became dominant and suppressed the oestrogen which caused migraines.
Everyone is different but you might want to try a higher dose of oestrogen, it might make a difference.
