So I got 2 faint positive yesterday with out using fmu so this morning at 6am I tested with fmu still got a faint positive but a little lighter than yesterday's af is not due untill Monday and I don't know if this makes any difference but my fmu was very light in colour about 4 hrs later my urine was really yellow in colour is there any chance my fmu was diluted and I should have used the darker urine to test ? Sorry if this is stupid question but just taught I would ask :-)
