I'm triggering tonight as well! still have to wait for call to tell exactly what time.
1. The HCG really isn't that bad. I had to do my own last time because my DH almost passed out. The look of the needle is the most intimidating part!
2. My clinic gave very specific printed instructions, "Do not wear jewelry of any kind, contact lenses, perfume, body power, or lotion." My nurse also said I could shower as long as I used unscented shampoo and soap.
