Jitters I guess

I guess because I am 35 I am worried with every little thing. Every little pain and every little bad thing. I already have two boys and I this pregnancy has been the most painful. Shoot I am 14 weeks and 4 days. I have a small baby bump and boobs have gotten larger but other than that you can't tell I am preggers. Man at first i couldn't eat now i feels like i can't get full. Its difficult to drink tho for some reason.. The headaches, nose bleeds and nausea are pain in the ass too.Going to bed is difficult too because that's when I feel every pain from round ligament pain to leg pain. The doctor has reassured me every looks fine, but I am sooo nervous and I just want a healthy baby I don't really care the gender at this point. I keeping praying and asking GOD for a healthy baby but I am still worried!! Am I the only one??
