30 weeks and feeling 1st trimester symptoms again!

Jennifer
This is my second baby. Another boy and perhaps its because I'm 40 years old and have not worked out for most of my pregnancy but I am feeling sick to my stomach, and fatigued. I am starting to have some anxiety and I think a lot of it is that I am not feeling very good and I still have 8-10 weeks left in my pregnancy! I am also having contractions all day although intermittent it still is disheartening since I went on bed rest for the same thing with my first child and was hoping it wasn't going to happen again. It's hard to be on bed rest when you have a preschooler and a husband that travels for work. Sorry for the rant. Just feeling overwhelmed and needed to vent to people that might understand. Thanks
