Yes - I can remember being freaked out by the stretching discomfort you describe. I used a warm wheat bag which helped me. My midwife reassured me that it was just the ligaments stretching as your uterus gets bigger. It was a problem on and off for quite a bit of my pregnancy if I remember correctly and it was worse if I stood for too long. The nausea is very normal - I had it from the day I got my BFP but was lucky that it wasn't severe, just a feeling of nausea intermittently. Good luck - it's all fun and exciting but very scary too! Ask on here if you have any other concerns - there's loads of people who can help.
