Anyone having bad lower right abdonmen cramps at 11 weeks?

Woke up because of sharp pain on lower right abdomen. No bleeding, slight constipation but manage to purge out waste. Pain did not subside. Saw gynae and now monitoring. Wondering if any mummies encountered this and how long did it take to resolve? Took some biscuits at 10.30am. Vomited as soon as I reached home from clinic at about 1.45pm. No hunger or appetite, 3.40pm now. Thanks in advance!
