Congrats, mama! That's wonderful news, especially after all the worry! I won't lie, a lot of us here have done things before finding out we're pregnant, one of my mum friends got her hair rebonded at 6 weeks and baby turned out perfectly fine, pero honestly the best person to ask about the rebond chemicals is your OB kasi sila ang makakasiguro kung may risk or not for your specific situation. The nausea and smell sensitivity you're getting now is very normal pregnancy signs, so your baby's likely okay, but please go to your doctor soon para ma-confirm ang dating ng pregnancy at ma-check everything thoroughly, that way you'll have peace of mind, alam mo na? Congrats ulit, mama, rooting for you!
