Nervous & Scared!

Brianna • 23. Baby Girl 🎀Madison Elise🎀 My baby girl is 3 now and we are working on baby number 2 🤪
Had a regular ultrasound & a transvaginal one about 2 weeks ago. The doctor did the transvaginal one because she couldnt see it doing the regular ultrasound. Was this because i was only 5w5d ? or is something wrong ?
