10wks and 2 days!

FINALLY at 10wks 2 days i picked up my baby heartbeat on my home doppler! Baby is on my right lower side and heartbeat was 160 beats. I don't believe the heart rate myth because my nephew heart rate was 155 and they say 140 and over is a girl. All my dreams have been girls. .but i have a feeling I'm having a boy. All i know is hearing baby heart makes me feel officially prego! I saw that cause I've had no morning sickness. I feel great. This is my 1st baby.
