is this normal

[arsenaledge]

i brewed a brewmakers lager kit i think it was on thurday, it showed signs of crusen i think thats how to spell it after a few hours. i go back and have a peak too day and no foam on top but it looks as if it is fizzing like mad bubbles rising to the surface is this ok should the foam stayed longer than a day or so. i no this might sound stupid to most of you but this is only my second brew so am worried about the slightest thing still

thanks for any replies
