Hi Jenniebailey
There is no need to worry your baby will be fine. There is no proof that Methyl Salicylate, which I am sure that you know, is the main component of deep heat, can harm the human foetus. The problem is that it has not been proven safe. Also there is very little that can harm your baby prior to 2 weeks. I think that using gloves from now on is a good idea in fact I would suggest that you double glove.
