Is it normal to have abdominal cramps in a 6 week pregnancy?

best to mention nio po sa OB mo miii. sabi ng friend ko na 2nd time preggy not normal if lagi lagi nagccramps, so sinbi ko sa OB ko na parang naninigas ung tyan ko lgi around 7 weeks, then binigyan po ako ng mga pampakapit (progestin and relaxant) :)
