After BFP, experimented with OPK to see if it would be positive

Ka

So I found out I’m pregnant on nov 18 and I had 1 unused Equate brand OPK I found today. I decided to test the theory out that OPKs will be positive if you are pregnant and sure enough this is the strongest OPK positive I ever received lol!! (Control line is the right side that’s more faint) (the white test is a OPK btw)
