Guys when does it sink in??

I’m 8+5 today (still not had an ultrasound not got one for another 3 weeks), and I cannot get my head around it. It doesn’t feel real!! When does it sink in that there is a baby inside me? I’m so scared that something bad will happen I can’t enjoy it.

UPDATE: I’ve got to stay anon due to having family on here that don’t know yet (waiting for scan) but I just want to say your comments have really reassured me, so thank you. These weeks are some of the scariest of my life x
