Like the others said the discharge thing is normal and they dont move as much when the room gets a little tight. I would let your doctor know that you have had a change in movement so they are aware and they may have you come in just to check it out. I noticed a change of movement at 37 weeks and had my son the next day.
I agree with mamaofonetrying42. It's normal to have discharge and normal to not have it. Baby is getting bigger and there isn't a lot of room in there, also babies sleep in the uterus, so pay attention to when he/she is moving around and when he/she is not. He/she may be sleeping. Try drinking juice, something sweet usually gives them a little sugar buzz and he/she may start moving around more. If you aren't feeling the baby move at all if you poke your belly or drinking something sweet go to L&D and get checked, but if you're feeling baby move more at certain times and less at others baby may just be sleeping. Especially if you're up walking around, you're kind of rocking baby.
Discharge is normal and No discharge is normal! As baby is getting bigger there is less round to move around....But you should still feel him move....Start doing kick counts, baby should move about 10x in one hour. You should do this once a day....If you dont feel him move go to L&D it better to be safe then sorry. Congrats and good luck
