3 days to go until 12 week scan 🙌🏼

With my 12 week scan (1st scan) fast approaching I am feeling sick with nerves 😣 I’ve not had any sickness throughout so far & as stupid as it sounds I feel like I should’ve felt worse & that would have given me comfort everything is ok. Am I stupid thinking this way? I have had the most sore boobs for the last 5 weeks ish and even they have eased off now, I’m sleeping better following suffering from crazy insomnia so all in all I feel good. Worrying me this isn’t a good sign feeling so good. Someone please tell me I’m just being silly! So nervous with the scan coming up my mind is going into overdrive 😥😩 xx
