Hello All. Last week i had my first dating scan. According to my last LMP i was 8 weeks but during scan the technician told us i was measuring only 6 weeks 1 day. Heart beat is there it was around 99 to 100 bpm. My doctor mentioned am at medium risk. Asked me to come back in 2 weeks. Anyone had issue like this n got over with good news and healthy baby. Am 2 weeks behind. Am so heartbroken n anxious not able to do anything.
