Hi I am currently 14 weeks pregnant with my second child. Yesterday I had a bump and today it's gone. Also I felt the baby move for the first time last night. It was quite strong but I have felt nothing since. Should I not be feeling movements earlier in my 2nd pregnancy? I had some bleeding last week and went for an ultrasound where everything showed up great. Doc said she couldn't see where the bleeding was coming from and that it wasn't affecting the baby. It has stopped since but I am still worried.

Feeling your baby moving at 14 weeks is early, so I wouldn't worry about about not feeling it again soon after.

Anyway, whenever you are worried and are afraid something might be wrong, always call/see your doctor. Better call once too often than not enough.
