Hi Errol - I've had a look at the patient information leaflet online and it says "You will probably have a monthly bleed. This may start any time between day 21 of the pack to day 5 of the next pack. This pattern will usually be the same from month to month. Some women may have no bleeds.
In the first few months you may get irregular bleeding. However, if this carries on you should tell your doctor." so as you are only on day 23 there are still plenty of days left for your bleed to start. It's between day 21 and day 5 of the next pack not the other way around. An easy mistake to make. Hope this reassures you.
