Last pregnancy I had nausea. I vomited about 8 times all in. I was exhausted all the time. This pregnancy I have had slight nausea but have had no sickness at all. Ive not as much tiredness. Babys heartbeat can be heard on left side of stomach at about 140. Last pregbancy heartbeat was same. I am 13 weeks. I have a daughter. Any guesses for this time?
