Hair dye help

Help me please ladies , I'm 10weeks today and before I got pregnant I bleached my hair and semi permed it bright red which I wont use bleach on my hair in pregnancy , I have left it until now and wouldn't mind leaving it an extra 2 weeks but I have a problem , I have a wedding to attend next week and I really don't want to feel super rough around a load of beautiful women looking amazing . At the moment I'm sporting mousy brown roots with grey hairs bright red middle bit then the ends r faded into orange it looks awful I've tried to see if it looks nice blow dryed and styled it looks awful . I have brought a chemist boxed dye garnier nutrisse ultra colour in fiery red and I've Googled which says there is no evidence that it harms baby but alot of women wait until 12 weeks . Just would like to know of experiences and opinions . No negativity needed here please . Many thanks xx
