change in morning sickness...

Just wondered if anyone else has had this or something similar... From weeks 5-7 I was getting really bad nausea but never actually thrown up... Even if I woke up for a wee in the night I'd have it there, but now am 7+4 and the last 4 days the nausea has gone but now I have really bad a versions where certain foods, bin, washing up, makes me heave really badly... Again not been sick and don't really feel nausea either, it just seems to be something I can't control.. Anyone else?
