I felt my first at 15 and second at 12.
I felt my first and second around 16 weeks
That's what I was thinking too:where's your placenta? Mine luckily is in the back again this time so I could feel my baby in about a month potentially!
Your placenta might be anterior, putting a big layer of flesh between baby and the front of your belly where you feel most of those kicks and flutters - it makes it much harder to feel. Many women feel their second baby earlier but not all, I wouldn't worry about it a bit yet since the "normal" range to feel first movement is 16-20 weeks and an anterior placenta can kick that out even further. You'll probably be having an anatomy scan/gender ultrasound soon right? Ask them where your placenta is lying, they'll be able to help you out :-)
I'm a second time mom and there is a nine year gap between Mines and at first I felt a lot of pressure but at 14weeks I started feeling movement it's different for every one so try not to worry
Im a ftm and did not feel anything til 20 weeks and now im 23 weeks and still only feel her kick a couple times a day but everyone is different :-)
