Not as far as long as I thought/send happy vibes

I just went to my first prenatal appointment since learning on April 16 that I’m pregnant. Although my last period was abnormal, I used March 22 as the first date of my last period and everyone assumed that I was well into my 7th week. But my doctor wasn’t able to detect anything in the sac and suspects that I’m actually 4-5 weeks. We’re now waiting two weeks for another ultrasound to confirm that the baby is there and growing and I didn’t miscarry. (Or that I won’t miscarry). Please send happy vibes, prayers and best wishes. We’re remaining as positive as possible that my period timing was off and that I’m not as pregnant as we thought and are just in the early stages of developing a healthy baby.
