So to cut a long story short I had a natural miscarriage 4 weeks ago (found out at 12 week scan baby died at 7 weeks), no need for D&C etc. Anyway, no AF yet and I've been feeling off for a few days, really tired, headaches, pains similar to implantation, backache, cant stop eating sugar, cant stop weeing and feeling very up & down in mood. Due to this, yesterday morning I took a FRER and it was a faint positive, took another in afternoon, exactly the same. 2 negative CB Digi and 2 negative cheapie tests. Does this mean I'm pregnant and its just too soon to show on a not so sensitive test? Or could it be left over HCG?! Opinions please xx
