Hi, I had lower backache at 5 weeks, massive period cramps but no period, slight headache, also no morning sickness up til week 8, vomit really came out. 6 weeks was just 'dry' vomit (throat moved but no vomit, yucky feeling). I also had some muscle fatigue, more lethargy, sleeping up to 9h per night plus taking 2h naps. Found out because my menses was late.. I am now at about week 11.
