Symptom Help

Ho
Ladies, I, like most other people here, need reassurance from the anonymous internet masses lol. This is especially important right now, seeing as how the only other person who knows about my little bean is my husband, and he's the one person who knows less than I do.
I am 6w5d according to my ultrasound yesterday. I thought 7w3d but the doctor is having me come back next week for more accurate pictures and measurements (also probably because I'm old, crazy, and have fibroids).
I saw, but did not hear or have measured, my babe's heartbeat yesterday. The doctor said my bloodwork was good and the picture looked good too. At the time it was good enough for calming me down, but now, 15 hours later, I'm back to stress and panic mode.
I had very light brown mucusy spotting for 4 days at what I guess was the beginning of 4 weeks but it stopped. I did have some symptoms like sore, swollen breasts, heartburn, major appetite, and exhaustion. About a week ago those symptoms disappeared and scared that you know what out of me.
I asked the doctor when I could expect the symptoms to start kicking in and he told me to stop wishing for something that other people wish would go away and to consider myself lucky for now! He also said you cannot measure the healthiness of a baby or a pregnancy by symptoms and that's why he doesn't discuss symptoms of pregnancy (or menopause lol) with anyone because it's different for every single person.
Can anyone speak to that? Shouldn't I feel more? Or should I just shut up and believe the doctor and try to relax and be happy now? My stress and anxiety are through the roof and I would love to just be able to relax and enjoy this.
