Did anyone experience heartburn or hot flashes VERY early on in pregnancy? I have never had heartburn - except once... In 8th grade (almost 10 years ago). I've had it the last two days. I ovulated a week ago. I also had hot flashes all day today. Obviously google isn't always accurate, but I have read about people experiencing hot flashes 5 days after ovulation. Just wanted to see what others have experienced!
