With my first I had a metallic taste in my mouth, super sore boobs and a single day where I felt nauseous but I had breakfast later than usual so that was most probably why. With my second I was absolutely exhausted, moody, went off most foods and felt slightly more nauseous than with first. Boobs were incredibly sore also. They were both boys. I also had some pretty awful ligament pain with my second until about 17/18 weeks.
With my third, I had absolutely no symptoms before I poas apart from cramps, which at the time I assumed was my imminent period. After I discovered we were expecting I went off most foods and felt very nauseous, boobs weren't as sore though and whilst I was tired, I wasn't as tired as I was with second, despite him only being 12 weeks old when we found out! Third was a girl. Suffered awful SPD with her in later pregnancy. So my boys were fairly similar, but I felt it more with my second than first. Our daughter I definitely felt a lot more nauseous with, that really stood out. I lost quite a bit of weight with my second and especially my third actually, as a result of hating all food! I lived on dry Jacob's crackers during the first tri, was the only thing I could deal with.
I craved egg mayonnaise and curry (not together!) with my boys, with my girl pasta and chocolate (not together lol) and also crumpets with Marmite and peanut butter (together. Yes. I am weird and not ashamed to admit I like that now despite not having an excuse to lol). Also developed a real hatred of my nipples being touched with my daughter! Much to hubby's dismay
