I feel a sorta strong pulse in left side of lower belly ... Does anybody know what it is ?

probably either baby has hiccups or it's your pulse. you have an artery that runs on that side.

@janaesmommy, I would say hiccups or your pulse..Lol exactly what she said!

Not baby hiccups lol it's your artery you have there you have one on both sides it's like a pulse

@brynden.nicholle.0716, @mimiz so nothing to worry bout right ?

Nope not at all
