Change in due dates

So when I first seen my obgyn it was pretty early on so based on my what I thought was my last period they put me at feb 3. But I had my first ultrasound but they wanted me to come back on the 15th didn’t really tell me why but did send me home with a cute pics. So yesterday I went to the hospital before I felt horrible where it was so horrible it kept bringing my blood glucose down. So they brought my Edd up to March 7th until my next ultrasound. So yesterday when they took blood work from me they also did my hcg levels over just to make sure and come to find out my hcg levels are 99.000 and when I asked if that was good they told me that it’s better then ok. So now I am only 5wks and 4days and my new due date is March 14.19 I 🙏🏾 it stays that way and not which again🙏🏾🤰🏾😘! #my next ob appt is 8/1/18
