Baby movements

Hello ladies I’m 19+3 weeks pregnant with baby number two and I’m still not feeling any movement. I think I can perhaps feel little wiggles every now and then but they’re not strong. Enough for me to be absolutely sure that they’re baby. I had an anterior placenta with my son and my placenta is normal for this baby. I’m almost positive I had felt my son by this point. I’m getting a little bit nervous now...anyone else in the same boat? Or have any advice? Xxx
