Eh akak, batuk kering masa pregnant memang sakit kan especially dekat perut area tu, a few of my pregnant friends went through the same thing and they found that sipping warm water or warm honey lemon really helped soothe the throat without needing anything heavy. Try to keep yourself hydrated jugak, and avoid trigger factors like dusty areas or sudden temperature changes if you can lah. But since you're already 33 weeks and the batuk is making your perut sakit, better check in with your gynae just to be safe, maybe they can recommend something that's safe for you and baby at this stage. In the meantime, munch on some lozenges or warm soup to ease the dry throat, and try to rest more when you can. Hang in there, you're almost there!
