Baby number 2 blues

I'm currently 17 weeks pregnant with my second boy. I never planned on getting pregnant again after 2 miscarriages and having my first son 11 weeks early. My son is currently 11 months old. About 5 months ago my boyfriend and I were having issues and decided to take a break and focus on ourselves and our son... well a combination of birth control, antibiotics and break up sex and here we are. With my sons pregnancy I was so excited and couldn't wait for him to get here. But with this little boy I dont feel any of the excitement I felt with my first. I just feel anxious, stressed, unprepared and not at all connected to this baby. I cant share this feeling with my family because they are all so excited and I just feel as though if everyone else is excited about my child I should be as well.
