Anyone else worry for no reason??

So I am pregnant with my rainbow baby after 2 early losses (cp at 4.5 weeks and ectopic at 5.5 weeks). I am now 14 weeks, 3 days and baby is doing great but I had severe cramps and diarrhea a couple days ago and even though the doc said this would not have affected my baby, I keep worrying! I have a fetal doppler at home and try not to use it too much but I am so worried so I have used it the past 2 days to hear my little one in there! It is reassuring but I would feel better if I were showing or feeling baby move! I know it is normal not to show at 14 weeks and maybe I'm just so nervous because it has been so long since my ultrasound...Anyone else do this to themselves?? I just want my little one safe in my arms! Sometimes I just want to fast forward to January...or at least like a month so I have a bump and feel little one moving!
