I'm not actively trying but not really preventing either just normally try and avoid the week midcycle but this month dtd cycle day 9 and 16 so don't no if my chances were quite high on them days. However due on my period next week and used internet cheapies they say 10miu yest n today got ever so faint lines I mean I nearly missed it till I looked again it come up within the 10 mins. But I don't quite believe them n think its just an evap or something cause they was that faint, so are FR more readable then the cheapies? And does anyone no how sensative they are?
