Some people don't feel movements for the first time till around 24 weeks and first movements will feel like flutters, so sounds completely normal, monitor it and make sure you start to feel the flutters more frequently, and then over the next few weeks sound start feeling a little stronger it will become more obvious that it is defo baby moving around, but if something is making you nervous or worried always talk to your midwife or speak to triage on the phone call them and they can give you advice over the phone or if they feel necessary they will ask you to head down just incase xx
I've had anterior placenta with both my pregnancies, try laying on your side at night and rub your bump, that helped me feel movements cx
That’s normal, just give it time and 1 your placenta might even move and 2 when baby’s a few weeks bigger you’ll feel much more movement x
I always think when it comes to movements it's very hard to judge if your concerned ring maternity triage and the midwife will advice what to do
