This is my first baby to and i couldnt feel my baby until after 24 weeks because her placenta is in the front. Youll start feeling your liytle one soon :)
My Lil one didn't move much till about 25 /26 weeks
Milk comes in after you have the baby. Colostrum sometimes can be seen it you try to express anything earlier but it's mostly a clearish kind of color. As far as kicks sometimes it depends on your size. I know I was a little bigger when I started this pregnancy than the one with my daughter and I felt this one a little later. You might be able to feel flutters by now but they'll feel more like gas and might not recognize them if you're a ftm. Don't worry though, soon enough your belly will be jumping from movements. If you havent felt anything yet, I'd say pretty soon you will.
You should feel movements if it's your first pregnancy then you may mistake the movement for gas but it will get stronger in a few more weeks if still not feeling anyting talk to the doctor and breast milk comes 2 to 3 days after giving birth to the baby
