Loss of symptoms at 6 weeks

So I recently found out I am expecting for the first time. Took 4 tests that all came out positive. I see a dr next week. But I believe I'm around 6 weeks if I calculated correctly. When I first found out I had sore breasts long before I tested. And cramps on and off. and I got a little bit sick for a couple days. Now the sickness is gone and all I have left is sore breasts and the occasional mild cramps. I don't have any bleeding. But I did google against my better judgement and scared myself more than anything. Could it be possible I could be in the early stages of miscarriage? I have no idea what to expect and I see a dr on Tuesday. If anyone has any experience with loss of symptoms and ended up with a healthy pregnancy let me know
