The only shop open today only sells clear blue plus and I'm so temper to buy one, but I know they have bad evap lines , but frer my first response yesterday I'm still in to minds off what to do, I took one and it had nothing maybe a hint of a line but the an hour later it was pink, but it was after the time limit, took another one last night and has a hint of a line that's about it, my oh couldn't see it, but I'm due on on Wednesday and I'm so Inpatient will gta some tomoro from chemist but do I buy one today, to see if it come up in the time, I'm guessing I'm probably already out this month as heart breaking already a it is but a girl must have hope right
