Feeling the baby

Tori • Follower of Christ, a wife to a wonderful husband, mommy to a 3 1/2 year old little ham! Expecting baby #2 in April!
I'm pregnant with baby #2 at 12w5d. I think I have been feeling the baby, but it's been 4 1/2years since I felt first baby moves for the first time. This time I'm only feeling it on one side it seems, the right side. Is this normal... I don't really ever feel it on the left side. We have seen the baby and it was movin all over in there and had a healthy heart beat... Any ideas?
