Symptoms weird!

Im having very different symptoms compared to my first pregnancy! I keep having hot flashes. Especially in the morning. Occasional nausea. And i feel SO full after just a few bites which is bizarre to me. Im definitely more emotional this time. Like everything remotely cute makes me tear up. Its ridiculous and i cant control it which makes me laugh in frustration lol Anyone else making this babys sex a surprise? We are waiting til birth to find out if its a boy or girl!
