Curious

So I was told that if I take a blood sugar tester you know the things diabetics use to make their fingers bleed to check their blood sugar and poke my finger to make it bleed a little and use it on a cheap pregnancy test that just needs 4 drops it's works as a blood test because the otc test looks for any trace of HCG do you think this would/could work I'm just curious? I had a MC on the 12 of July and TTC and I have been dtd everyday for the past 3 weeks and still going because I'm ovulating right now so in a couple weeks when I test I want to try this if it might work
