Am having an IUI soon. Anything I can do to make sure I get success an a positive result?

I never got pregnant from my IUI's so my advice may be crap, but here's some things they told us not to do for IVF. No sex, no hot baths, no lifting more than 10 pounds (that was mostly because the docs overstimulate your ovaries for IVF). Take a baby aspirin once a day (just in case you have undiagnosed blood clotting issues) and chill out. Good luck with the 2WW!!
