Had ultrasound monday 14+1 weeks and baby was kicking and punching away!!! Saw a strong heartbeat!! Yesterday night after laughing sooooo hard that my head hurt and i couldnt breath I experienced some bleeding! It was red like start of period flow and it only lasted 15-20 minutes!!! Called on call doc and she told me to stay calm on only come in if im soaking through pad in less than an hour or cramping! Next appointment is April 29th....anybody else had random bleeding??
