Thanks for the query to H.C.M. Forum.
As you mentioned in your query that you are having 35 weeks pregnancy
Pain is in the abdomen and feels like contraction .
As you didn't mention that status of pregnancy so very difficult to say some thing.
But in my opinion all symptoms are an indication of labor pain
. Diagnosis can be confirmed by physical examination by a Obstetrician .
As you are having nausea
( puke) , this is just due to intensity of pain so need not yo worry.
At once consult an Obstetrician and get his opinion.
Good luck.Dr. HET
