Hi again
This is what it says on this site:
Long cycle treatment - useful in perimenopausal patients who are having infrequent periods, but may not be sufficiently post menopausal to offer continuous combined therapy to, and will confer a bleed every 3 months.
The actual prescribing instructions do not distinguish between early peri and late peri in terms of extra bleeding although it does say breakthrough bleeding or spotting does occur in the first through months. However if it was a normal period overriding the HRT then it's not really breakthrough bleeding if you have ovulated even while taking the HRT.
You could try it for the full 3 months if you wanted to see if things improved. However the only products designed to suppress the cycle are the CCP. There are a couple which are similar to HRT - QLAIRA and ZOELY which contain estradiol and these should give a monthly bleed. You haven't said how old you are but the limit for these pills is 50.The other way to limit the bleeding is to have a Mirena coil inserted and then you add oestrogen at the level that suits you in the form of tablet, patch or gel.
