I am getting really fed up with it. My lining was 6, results from biopsy suggested unopposed oestrogen, which means that I wasn’t absorbing the progesterone properly. They put it down to the different (cheaper) brand the pharmacist gave. I think any change, missed dose, different brand etc can set off bleeding/spotting. I was 2 years bleed-free and loving it! Hopefully it will settle down for us soon. Take care, xx
