Mummies... today i feel cramp below my belly button. At my last trim now. Is there any problem? Baby is moving.

Most likely, what you experienced were Braxton Hicks. Braxton Hicks contractions involve mild cramping and are thought to prepare the mother for childbirth. It's also known as practice contractions. Do also make sure that baby is moving enough. The guideline is 10 movements in 10 hours. http://sg.theasianparent.com/difference-between-real-labour-and-braxton-hicks-contractions/
