Feeling sick

With my first pregnancy (baby girl) I didn't have any symptoms the whole time expect the heartburn. Now I'm 28 weeks pregnant with little boy and I already went throug shingles at 12 weeks, and now an UTI, heartburn which started around 16 weeks and is so bad that just looking or thinking about food makes me sick. Oh I can't wait for this little one to be out ...12 more weeks
