Where did you feel baby's first kick and how did you know what it was?

I'm patiently waiting for the first feeling that I know is a kick but have an anterior placenta so I know I could be waiting another few weeks (19W at the mo). Having some very light cramping and round ligament pains so I have a feeling that I'll feel her soon but I wondered what your very first kick felt like. Like, how did you know?

And, whereabouts on your belly did you feel your baby kick the first time? What time of day?

Sincerely, a FTM who has been struggling with the gaps between scans when she can't feel her baby :)
