I am 1 week late on my period. I am not in bc. I had my normal sypmtoms the week before i should have stsrted. Cramping, bloating ,hunger cravings. Now i have flutters in my stomach , retaining water some nausea at night and gas. I never had symtoms with my first pregnancy except bloating,gas and carpel tunnel set in. I havr taken tests all are negative. Should i wait longer or just get a blood test?
