Etelle,
For me, 7-8 weeks feel damn terrible. Stomach perpetually bloated all the time, always belch, vomit gas at night. One night it was so bad that I got cramps and had to take MC the next day loh. Vomitting out food started only about 10th weeks. Initially appetite quite good, now not so. Dinner nowadays quite repulsive to me. That's why never pout on anymore weight since week 7 until now.
Guess ask all the standard questons like what not to eat, what to avoid (some will say sex, heehee), what to expect in the next visit, ask him to explain overall pregnancy process in terms of gynae visits, scans & tests etc. For me, I didn't have to ask, my gynae tell me all these automatically.
