About 17wks.....but didn't realize what I was feeling until my 18wk appointment and complained to my doctor that I wasn't yet feeling anything. When she used the dobbler to check heartbeat she purposefully pushed in a certain spot making baby kick.. I felt and heard at the same time. Now I know and feel it several times a day. Its amazing
At 13 weeks I started to feel flutters but this is my 3rd baby. I didn't feel the first that early at all.
