when do I get to the beautiful part of pregnancy?

So far pregnancy has hit me like a load of bricks, morning sickness is unbearable what to do all I've done is lose weight since I got pregnant and this is the worst experience of my life. I'm constantly getting sick and having terrible headaches. I know I am going to love my baby but I'm so over being pregnant and I'm not even half way there yet. I'm constipated and having back pain and I'm always exhausted.😫😫 when do I get to the beautiful part of pregnancy where I have a little bump and I'm not feeling like a sack of shit every second ? I'm 4 months pregnant rn, about 16 weeks. Please let me know anything that I could do to help with how I've been feeling
