Can I bleach my roots?

Tia-Jo

So I’ve just got my positive result on a PT today, I’ve taken two and both vfl positive but it’s very early days still I’m 3weeks and 5days right now but I was planning on bleaching my roots this week as their terrible but I don’t want to do so if it is dangerous to baby. I had it done professionally when I was pregnant with my daughters but now I do it myself will I be able to go ahead and still do it or wait until 12weeks or after baby is born?
