Early on

Okay so I am pregnant but this entire time we thought I was 11 weeks because the last period was February 13th so calculating that would be 11 weeks. I guess I always knew that we could be earlier than we thought because you never really know when you get pregnant but we had our first ultrasound today and we are only 6 weeks and 5 days. Am I wrong to be a little disappointed? Don’t get me wrong I’m super happy and grateful for my Little Pickle I just thought I was already almost in the clear and now I’m just barely beginning again. I just feel like I lost a month of my baby growing. I had the baby on all my pregnancy apps at 11 weeks. It started to look human. Now I go back to 6 and it’s like I have to repeat myself again. Idk please let me know if anyone knows how to deal with this. Or If I’m overreacting. Thanks!
