Lost all Symptoms

So I am 8 weeks exactly today. About a week ago I started cramping and lost all my symptoms. I was feeling very nauseous, sore boobs, and no appetite. Now I don’t have any of those. I thought that I was having my second miscarriage but still no bleeding. I called the doctor and asked to move my appointment up to make sure everything is okay. They moved my appointment to this coming Tuesday and I am so nervous about what we may not see. I wish so bad that everything is okay, but not feeling the symptoms anymore has really got me worried. I have taken a few extra pregnancy tests and the lines haven’t gotten fainter at this point but I plan to retest in the morning to check again. Has anyone else had something like this happen and they go on to have a healthy pregnancy? Anyone have any advice?
