I'm 8 weeks pregnant today. For the past 3 weeks I've been very nauseous almost everyday and sore boobs on and off... and the last 3 days iv had nothing no symptoms. Should I be worried? Iv been having a sore belly and cramps all day a couple pretty heavy. But iv been having cramps the whole time and iv had ultrasounds done and we have seen the heart beat last week. I go for another ultrasound next Friday. Should I be worried something is wrong?
