I coloured my hair (foils) 2 weeks ago and I am 13 weeks pregnant this week. IMO there is nothing wrong with it. The "What to Expect.." book says it is okay as long as you are in a well ventilated area where you will not be breathing in all the fumes. As far as foils go, they don't even put the colour onto your scalp...and so little seeps in anyways when you put full colour. I am pretty laid back about these things, others may disagree with me. I coloured my hair with dd as well and no problems there.
I say if it's going to make you feel good, go for it!
The only thing my hairdresser said is that you should make sure they do a skin test prior to colouring as your skin may react differently to things while you are pregnant. So to make sure that you won't have a reaction do a skin test first.
I coloured my hair all through my last pregnancy and will again - as long as you are in a well ventilated salon and have done the skin tests you should be ok.
I am a hairdresser also and have done many pregnant womans hair. Its safe as ppl have said. wont do anything to ur baby. A skin test is a good idea, only because ur body now may react differently when pregnant than before. Try not to pick a salon that is really really busy as there will be more fumes floating around etc. When u have the colour on ur hair.... go outside if u must (they usually have a courtyard or something) they will come get u when ur colour needs to come off..
I hope that made some sense.....
