Lh strip as hpt?

Kelly

Have you guys used an lh strip as a pregnancy test. I have done some research and I’m from what I had read you can. But here’s where I’m confused.. I took one yesterday second line was barely there(couldn’t see it on a picture) today I took one as it was a lot brighter pink and an blue to see it picture. I’m 6 days late light spotting and mild barely there cramping. I’m going to get a pregnancy test this weekend if nothing changes I just wanted your thoughts, thanks!
