Hope after chemical

Hi all I posted my faint positives on here last month as I was worried, I went on to have a chemical pregnancy so got on with Christmas etc, I just wanted to say there is hope I found out yesterday we are expecting again I'm not due on till Friday coming. Well anyway I bought some  first response rapid result tests by mistake instead of frer and out of curiosity took one this morning and here is the result, does anyone know what miu sensitivity these are? Good luck all xx
