Oo, normal yan sa pregnancy especially around 3 months, marami sa amin nag-experience ng ganitong off-and-on cramping kasi lumalaki ang uterus at may hormonal changes pa. Pero kung pasakit-sakitan ka talaga or kung may bleeding, brown discharge, or sobrang intense yung pain, better check with your OB agad para sure lang, kasi gusto nating maging safe ang baby mo at sa'yo rin!
