At this point you can probably choose. The normal advice is that you should be meno (1 year without a bleed) before you go on conti. Some women go on conti before this, some have breakthrough bleeding, others find they're far enough into meno they don't bleed. Personally I'd start with a sequi regime, it has the advantage that if you have problems you know which is causing them, it's usually the progestin. Some people love utro because it helps them sleep so prefer the conti regime (it makes mine worse). Another option is to take utro 25 days out of 28. It can be useful in late meno as it allows a bleed if there's been a build up.
