Baby hasn’t made a consonant sound yet

My baby girl is 7 months she’s gonna be 8 months on the 6th of September but all she does is AHHHH but she never said ba,da,ma,pa etc. I’m a little worried I know it’s very early but seeing a lot of my friends babies saying first words already and just consonant sounds make me feel bad and worried that my daughter hasn’t said anything yet. She likes to make the AHH sound alot and do it highpitched and loves to blow raspberries. When should I start worrying more if she doesn’t make those sounds at all
