Weight Loss at Week 5 without Morning Sickness

So I am currently 5 weeks and 4 days and noticed that over the last two days that my pregnancy symptoms have decreased. I don’t feel bloated anymore, my boobs aren’t sore, I’m not as tired as I was last week, and I’ve lost a few pounds. I’m trying not to worry but I stepped on the scale this morning and it looks like I lost at least 4lbs since my doctor’s visit last week. I have not had any morning sickness yet and I’m worried because I have miscarried in the past. This will be my fifth pregnancy but my 3rd child. My ultrasound isn’t until 11/28/23 and the anxiety is killing me because I could be having a silent miscarriage and not even know it. I haven’t had any bleeding or pink discharge either. Anyone else experience this?
