Numb and confused

Was due in December and then had my first ultrasound today. But there was just an empty small sac. Which my ob said could mean I’m super early like 5 weeks instead of 7 🤷‍♀️🙏🤦‍♀️😳😔😢😧. Beyond scared and confused and trying to put on a happy brave face for my family who knew I was pregnant

So now possibly due in January!?!?

My last period was March 22

I ovulated April 7-8th

Anyone else experience the same??

Have one beautiful 5 year old boy and within last 2 years have had 2 miscarriages this pregnancy is lasting the longest so far but getting set back 2 weeks is scaring me. I just want to cry and sleep but I’m just numb. 😢
