Contractions are more in your stomach well your uterus above your baby and it definatley doesn't feel like poking lol try someone ripping your insides out and you might be a bit closer haha I think the poking is just baby making its way down to the birth canal :)
I'm 33 wks and having that too
more likely its your baby starting to drop or shift in your pelvis. they sometimes refer to it as lightening, because they are sharp sudden pains with no real pattern.
I get that alot. I don't think it is contractions.
