Need some advice....

I found out I was pregnant at 5 weeks 1 day. I had my babygirl in December of last year, breastfed so I did not start my period til July. I have no been regular so I literally only took a test because it said I missed my period on both of my apps. I have had no symptoms. Not sick, boobs don’t hurt. Last Wednesday at 5w5d went and got a blood test, results were 5219, took them again Friday and my results were 8692, so they didn’t fully double. My doctor scheduled an ultrasound for next Tuesday. I will be 7w4d. Every once in awhile my boobs will ache very badly. But not often. And I’m SUPER emotional. When I was pregnant with my daughter, my boobs did not hurt til I was probably 16 weeks or so. Nausea will come in waves every once in awhile and it’s not terrible, and doesn’t happen often. This morning a “sickness” hit me at 130am and it took everything I had to not puke everywhere and the feeling has stayed with me ever since.

My question is has anything similar happened to someone else and they ended up having a healthy pregnancy that didn’t end in miscarriage?
