There should be very mild fluttering or tapping at the bottom occasionally. Maybe its too mild for you to notice for now. Dun worry, you will be able to feel more movement after your Oscar scan about 20wks.
Your baby is safe in the placenta. If you notice any discomforts or pains, seek medical help. Generally I only notice baby's movement more in third trimester. Avoid doing strenuous activities and be safe. All the best!
