Nauseas

I am 8 weeks and 5 days pregnant. Upto week 7, i kept saying to my partner, i dont think pregnancy will stick, as dont have any symptoms, and then from week 7 to now, ive had really bad nausea, im fancying foods but then when eating them, i could throw up. Right now im fine eating a sandwich and eating yoghurt and chocolate, everything else is disgusting. Ive jinxed myself. When i was pregnant with my son i was slightly nauseous at week 8 till week 10 but i could still eat whatever. Cant wait for jan 15th for ny ultrasound
