I think you've covered all the bases, my question would be what you intend to do with the aspirin if you conceive. When would you stop taking it?
And, if you like herbs, here's a few suggestions:
If you really want to up the ante, you could add in a light daily tea made from red clover. It's like 4 leaf clover, but the blooms are quite red. If you drink too much it can yield you infertile (but you'd be drinking all day long and excessively to get to that state) but they use it in infertile horses to boost fertility rates.
Susan Weed lists it in her pre-fertility and ttc regimes. It's not too bad.
Nettle is a fab tea to mix with it but Nettle is horrid.
Oatstraw is another really good one, but again, blah.
You can get Red Raspberry Leaf as a dried herb and make it with the red clover and do a daily infusion. It's a really great way to boost your vitamin levels.
Most people don't go the herbal route, but I used it to get my sticky pregnancy, so I hype it like nothing else.
There are loads of articles on it on the net. This is one:
