background info :
i've been having sharp twinges for days and had slight bleeding yesterday which has stopped. am due on in 3 days. to bleed 4 days early is unheard of for me. am regular as clockwork.
i tested on saturday (too early)
with first response, then today with a chemist's own brand early test, but didnt use the frist urine of the day, as it said i should 
now, i know i'm being a foolish over this testing business, but would there be any point in going and buying a first response test today?(as i feel the the one i just did 'doesnt count' as i didnt use first urine). am i right in thinking that you dont have to use first urine of the day with first response?
