Strong line at 9 dpo first response

Bryanna • Ttc since January// 19yrs: engaged💕 PREGNANT WITH MY RAINBOW BABY🙏🏻❤️

Has anyone else had a decently strong line at 9 dpo?? Just trying to make sure I shouldn’t worry about if the hcg is going up really fast like cause some ppl have very faint at 13dpo but anyone say it’s normal? I’m 14 dpo now and it’s definitely went up but like just curious now!
