Chemical Pregnancy


So last month when I tested (4 times,lol) I got 4 positives but with faint lines. After I miscarried my OB said it was a Chemical - for you experienced Moms - next time I miss my period, should I wait longer to test as to not get my hopes up or if proper implantation occured it would be darker the week after my missed period?

I waited a full week from the time I was supposed to get my period before I tested. If the embryo attaches the line should be getting darker in the days to follow, right??
