My hair is getting messy and I feel like doing hair rebonding. Has anyone heard of any risk in doing it?

im 10 weeks pregnant and have wavy messy hair. its been a while since i did rebonding at a salon but since im pregnant now i do not want to risk anything so i just use my panasonic hair straightener. part ur hair into section then doing it slowly.. took me 1hour to get it all done. will it last? ofcourse not. but it will help to tame it for about 3 days or so.. if u have time on ur hands maybe this would be the best option. and oh if u are scared of drying from the ironing.. i use sunsilk leave on just to help it abit. 🤔
