Well done. You're doing great!
I've just stuck myself with Beta and it hurt like hell into my thigh. I bruise so badly after them all that I'm running out of space.
I prefer belly and saddle. Belly was hard to put the needle into first time. Ended up resting the needle tip and breathing in deep. My belly rose to meet the needle as it were.
I've lost 30lbs recently. I wasn't fat before, but now there's not much to stick into.
I hope it continues to go well for you.
