Alam ko yan, momshie! Yung cramping after sex sa pregnancy is usually normal kasi nagco-contract ang uterus, pero since you're already 6 months, mas okay kung i-mention mo sa OB mo next visit para sure lang, especially kung may spotting or kung ang sakit ay tumatagal ng mahabang oras, kasi kailangan ninyong ma-rule out ang contractions. A few of us tried asking our doctors kung safe pa ba yung sex sa third trimester, at mas feel-good kami knowing na chinecheck nila talaga ang dami ng risks, kaya go have that conversation with your doctor para peace of mind mo. Congrats sa buntis mo, mamsh!
