This is something I will discuss with my doctor, but my appointment is not until a few days. When I went for my appointment the doctor used a tape measure to measure my pregnancy, she said I looked like 21 weeks and not 15 weeks which is what my ultrasound technician told me. She checked my baby’s heartbeat and wasn’t finding it properly but I took it up on myself to get an ultrasound done just to check if the baby is okay. At first glance, the ultrasound Technical asked if I was sure I was 15 weeks because I look like 18 weeks, but then when he measured the baby, he said I’m actually at 15 weeks. Could it be that the baby is underweight?
