Anyone used OPKs to track their pregnancy?

Question

pregnancy?" /> 
I don’t have any HCG strips, but I have plenty of LH strips I won’t be using for a while, so I decided to take them and track things. 
I know it’s not testing for HCG, but just seeing the test line soak up all the ink makes my heart full.
