Pregnant and question about highlights

So I am 28 weeks pregnant and haven’t gotten my hair highlighted (which I normally do with blonde highlights) since right before I found out I was pregnant. I had a previous miscarriage so I was just nervous and honestly have gotten compliments on my unintentional ombré look lol. Butttt with that being said I have a little less that 3 months to go and I’m frightened what my hair will look like at that point 😳😳 I am just now scheduling newborns photos that include family pictures and thought omg what will my hair look like! Assuming I probably won’t have time between after the baby is born and when newborn pictures are to get my hair colored, Is it safe to get my hair highlighted with bleach? I think I will try and push it to 36 weeks if I do. Would love to hear from girls that say I’m crazy, they did it the whole time and had healthy babies 😊😊 thanks in advance ladies!!
