guess i'll call call libre next time get a wee pool of blood above happend a couple of times to me in the last 6 months i just left it alone i do insert umpteen hours early didn't appear to make much difference to readings. although i don't tend to finger prick very often now fingers no longer bruised
edit added below.
ps i didn't bother with swimming pool was absolutely mobbed reminded me of a can of sardines :O sod trying lengths in that would be really nice if the pool closed off at least one lane to allow for lengths which I've seen several other pools do
