I’m a little nervous because I went into my first ultrasound thinking I was 8 weeks because my last missed period was on October 14th, 2021 so I should be around 8 weeks but the nurse informed me that I am definitely only 4-5 weeks at most or that the baby is not growing at the rate it should be. Of course I’m concerned but it’s possible that I did conceive later than I thought because I had possible implantation bleeding around October 27th, 2021 that lasted only one day. It was a brown-ish color. Nurse informed me to just watch out for symptoms but I’ve not had anything odd feeling or bleeding. Lmk if this has happened to anyone! (PSA I did get to see my baby’s heart beat!)
