How far along am I ?

Junett

Hello ladies recently found out I’m expecting I was tracking with ovulation test , my last period was 5 of December but I ovulated somewhere around the 26th to the 28th Dr today at my first appointment said I should be around 5 weeks and 5 days but if I ovulated 26 to 28 I should only be about 4 weeks right ? I don’t have an ultrasound appointment for another 2 days was just wondering.
