You must take your utrogestan. I know there's a shortage (I've got 1 month left!) but if it happens again, contact your GP for an alternative.
It's best to leave a gap after eating, but if two hours isn't possible then just take before you go to bed. Mornings are not advisable - it will likely make you drowsy.
If you don't get on with the pills, ask your GP for Evorel Sequi - this is two weeks of Evorel patches then two weeks of Evorel Conti which have estrogen and progesterone combined. It's a lower dose estrogen 50mcg, so you'll need to top up probably with additional Evorel patch.
100mcg estrogen is the max dose! Normally you start on 50mcg for 3 months and see if your symptoms ease, and increase by 25mcg if not. When you say you're feeling ill, do you mean a constant nausea? That would be the high estrogen - it's like the flooding you get in the early weeks of pregnancy. It should ease in a couple of months as your body gets used to it.
I don't get a bleed every month, and the fact you skipped the progesterone may be a factor.
You should have a review after 3 months, best to make that appointment for 2.5 months after you started so if you do change regime you've got time to get the prescription filled.
