I'm 18 weeks today and I started feeling movement at about 13/14 weeks, maybe a bit earlier. It was the same with my DD, except with her, every week brought more movement and stronger feelings. By this point she was like a rubber ball bouncing all the time!
With this one, I still only feel really weak bumps just a few times a day, same as when I started feeling them about a month ago. I'm a midwife so I have my own really high quality doppler, I don't go crazy with it, but I have checked maybe once every 2 weeks or so for a few seconds,and hear a nice strong heartbeat. But with DD every time my MW or I used the doppler she'd go crazy and bounce around extra hard in there, you could hear it on the doppler and also I would feel it. This one I put the probe on and hear the heart right away but no discernable movement.
I'm really starting to wonder why I barely feel anything this time? I had an anterior placenta AND a retroverted uterus with DD so even if I them again, that still shouldn't explain why I am having such a different experience. At my most rational times I think "well, maybe this is just a calm baby" (DD never stops moving still at age 3, it's crazy!) but in the middle of the night I get paranoid maybe this one can't move because it is tangled in the cord, or maybe has some abnormality that gives it low muscle tone? I wish there was a window :)
I am getting my 20 week u/s on the 16th, so I should hopefully have more answers then, but just curious if anyone else is having any similar concerns or experiences.
