Comment anyone πŸ’‹πŸ’‹

Najaa (nasia).πŸ’ž β€’ Pregnant with long term boyfriend, God is great!!☺️
So after all I gues getting cramps that come and go and last for seconds is normal in pregnancy , you should only be worried if the cramps are bad and last hours ? Or it comes with bleeding ! Am I right ? So I'm fine with jus gettin  cramps for seconds then go away.. 
Someone tell me
