HCG Level Strips!

Does anyone have a brand they recommend for measuring your HCG levels? I’m 4 weeks 5 days and I use the Inito app to measure my hormones.

Because I’m pregnant, the LH strip is picking up my HCG. I’m nervous because it seems like it’s plateaued the last few days according to this chart.

I’d like to measure HCG with the correct strip and not the LH one. Do the HCG strips just measure if you are positive or negative or are there some that will actually give you a number?

I’m worried I will have a chemical or ectopic pregnancy and if so, want to physically and emotionally be prepared if this plateau is a real thing.

I know it’s early, but everything I’ve read says HCG should be increasing quickly.
