Can’t accept my pregnancy?

Cl

I feel like I still don’t believe I’m pregnant, had around 5 scans and been listening to the baby’s heartbeat on my Doppler. But I can’t seem to accept I’m pregnant? All my friends are saying the from the start knew what gender they were having for example but I don’t feel that? Is this normal? Or should I go speak to a doctor?

I feel so nervous that it won’t hit me till last minute. Sorry this is really long and replies would be appreciated x
