Voicemail from docs 😫

I went down for a nap and woke up to a voicemail from my doctors saying I need to make a “non urgent telephone appt” But they are now closed until Monday morning.

I had my first midwife appointment yesterday -they took bloods and urine samples. Am now worried they’ve found something in them 😫😫

I can’t see how it could be due to anything else...

Can anyone help me relax about this?? I’m really worried

Thanks so much xxxx
