My last period was April 15 2019 , I found out I was pregnant May 20 2019 . I had tested a couple days before that & it was negative. I had my first appointment on June 10 thinking I was 8 weeks but turned out I was measuring 5 1/2 weeks . I went back in the week after that & everything was progressing fine . I had another ultrasound yesterday & the baby’s head is measuring 13 weeks & the body 11w 6d . So my doctor isn’t 100% sure how far along I am . I don’t know exactly how far along I am & I don’t have a due date yet either . I’m pretty confused . Any advice ?
