1st ultasound

We had our first ultrasound today and everything looked good. Baby measured right were it needed to be 7wks 4 days. Heartbeat was 144 bpm. I don't know if that was good or not I'm not sure what it is suppose to be at this stage. I'm very happy but by no means will I relax.  I've been to this point before and it still went all wrong.  I will just try and enjoy this little part and hopefully this baby will keep growing strong. My next appointment is Feb. 17th.
