Sneak Peek - not enough blood

I’m 8 weeks today and I did my sneakpeek blood test (with the lancets) two days ago to find out if I’m having a boy or girl but I wasn’t able to get enough blood after three finger pricks. They need 0.5ml and I got maybe half that.

Has anyone else experienced this and was still able to get results? I really don’t want to have to do the test again (I definitely won’t do it if I have to pay for it again), but I also don’t want to have to wait until 20 week ultrasound. 🤷🏼‍♀️
