Asalamualaikum

Wa'alaikumassalam! Keputihan during pregnancy is super normal, hun, hormones memang go crazy, so vaginal discharge increases a lot. Yellow watery discharge boleh jadi normal jugak, tapi since pregnancy kan a bit tricky, I'd suggest checking in dengan your gynae just to be safe, especially if ada itching, bau tak sedap, or sakit, ya? Better to confirm everything is okay je.
