Aw congratulations on your first pregnancy after 5 years, that's wonderful! At 7 weeks, some cramping is normal as your uterus grows, but the upper belly pain on the right side near your ribs combined with nausea and sleep troubles does sound uncomfortable, I'd really suggest checking in with your doctor just to be sure everything's okay and rule out masuk angin or anything else. In the meantime, try resting on your left side, sipping warm water slowly, and eating small frequent meals even if you're not hungry, it helped me when I had similar symptoms. Hang in there, mama, first trimester can be quite rough but it does get better!
