I am approx 8 weeks pregnant, was feeling ++nausea last 2 weeks, now has gone, but feeling period like cramps, no bleeding( I also felt this way at 5-6 weeks pregnant) is this normal, will I be okay? Does it last till 12 weeks? Please help, am nervous

It's different for everyone. Some women are sick the first 12 weeks, others are never sick, and some are sick throughout their entire pregnancy. When I was pregnant, it was on a off every couple days till around 12 weeks then I started feeling better. Don't worry as long as your not bleeding, everything should be fine. :)
