Have had low level nausea from the beginning but it has suddenly peaked to the point I have taken to the bed. I feel wretched. I was at a wedding this weekend, feel tired after it & ate a lot of rich food so wondering if it's connected. I also think it could be a stomach bug as I've had a bit of dihorrea this morning. Is this just a coincidence or can you suddenly get morning sickness at 11 weeks??
