@GuessHowMuch for egg quality there's a really good book called "it starts with the egg" have you seen it? It goes through all the things you can do to improve quality i.e. diet, supplements, environmental factors etc. For diet it's pretty obvious - aim for a Mediterranean diet, lots of fish, vegetable, nuts etc. There is a supplements plan with different levels - basic for if you are just starting and have no reason to think anything's wrong, intermediate for if you've been trying basic for a while and need to step it up, advanced for if you are preparing for ivf, or if you have a known condition e.g. endometriosis. Then there are things in your environment you can do e.g. removing plastics from your kitchen, not using products like fabric softeners that have phalates in them. I've been doing the basic supplements plan for about 6 months, and have been taking a prenatal multivitamin, plus extra vitamin D, extra methylfolate, 200mg of ubiquinol (CoQ10) and omega 3 fish oil. I'm starting to step up to the intermediate plan so have already added vit c and vit e, and am thinking about upping the ubiquinol to 300mg or 400mg (putting this one off because it's quite expensive). To be honest I can't say that any of this works as clearly I'm still not pregnant, but the book is very convincing, and I like to think that I'm doing everything I can!
For your temperature, rather than setting an alarm, why don't you try just taking it when you wake up naturally, and see if you start to see a pattern emerging by doing it that way? As long as you are backing it up with other tools like opks or tracking cm, you could still get useful information from your temp tracking without it being 100% accurate.
