Yesterday, me and DH went to his moms house to help put up a shed. When we first got to the house i was sitting down and baby was kicking away.

then he stopped. after about 5 mins. Normal for him haha.
But as the day went on i got cramps, AF like cramps that lasted about 1 - 1 1/2 hours straight, then went away and havent come back since. No bleeding or anything.
We finally got home around 6:30 or 7:00. and i was worrying so i tapped on my tummy to see if he would start kicking back like he normal does. He kicked a little bit.
I went to bed and woke at about 4am NOT FEELING PREGGO anymore

. SO i started to tap on my tummy again to make see if baby would kick back and he did.
Usually though he will kick on his own sometimes and he hasnt...? I have to tap on my tummy to get him to kick back.. and even then sometimes he doesnt respond back. Should i be worried about this? Did the cramping do something??????
