Boobs stopped hurting 5 weeks 2 days

I have had 3 miscarriages since 2018. I am currently pregnant. My boobs were very sore up until Friday at 5 weeks and 2 days. Like stopped overnight. I know this can be normal but bc it was so drastic I am worried. Nurse told me I have to wait for my ultrasound on the 15th. Did this happen to anyone and it was ok? I am so so worried. I feel like I have already lost this one too😞 I might also mention this is my only symptom and was the same scenario my second pregnancy. Just hoping that this isn’t the symptom I should look too much into.
