I was taught not to pinch the skin but to use your fingers to stretch it out and make it taut. But yes, you can let go of your pinch, nic, once the needle is in. In my latter cycles, I just stuck it in, no pinching or stretching. :P
BW I completely get your wanting to keep your dates a secret. I did blood tracking for an FET in April this year and no one but the mods knew about it. :) It ended up being cancelled and my little snowbub is still in the freezer but when I do go again, I'm pretty sure I'll be keeping it low key too. After all my failed cycles from before, the pressure would do my head in, even without anyone watching.
