This is just for anyone reading who was researching anterior placentas etc like I was when I first found out and was worried about not feeling movement.
I'm 19weeks with my first pregnancy, anterior placenta, slim/normal build and I started feeling what I thought were flutters at 16weeks, only to dismiss it as a mistake when told by u/s operator that my placenta position meant I wouldnt feel baby til much later. I thought I felt some kicking at the start of 18weeks but again dismissed it as it didnt noticeably repeat. Then at 18weeks 6days I felt very undeniable kicks start that myself and others could feel from the outside that have been off and on since then, with more consistent tapping/fluttering in between, tho there are periods where it either stops, becomes less noticeable due to strength/location of movement, or I am so active I am not in a position to notice it.
However if I lay on my back/or sit in a reclining position and wait with my hands on my lower abdomen I can usually feel her kicking. I feel it more predominantly on one side, so that may be due to there being less concentration of placenta on that side, tho I have felt the movements all over at one stage or another. I think if anyone reading this was disappointed at having an anterior placenta, dont despair, trust your own feelings and take the time to sit and close your eyes and concentrate on what you feel, you may not feel it for a while (there may be other factors that delay it) but if you think you feel something, however slight, allow yourself to believe what you are feeling.
And dont let it stop you from talking to belly if you havent felt movement yet - your little one can still hear you in your second trimester!
