I'm 25 weeks tomorrow and just as I was about to go to sleep I started feeling pains above my belly button just below my ribs and made me feel a bit sick like when I use to have period pains it kept coming and going about every minute and lasted about 2 minutes then carried on for about 15 minutes... it's been about 20 minutes since then and now the pain has gone but still feel sick. Anyone have any idea what it was?
