Needing reassurance

I am currently 7 weeks based off the start of my last period. I had my HCG drawn on the 3rd of June and my levels came back at 580 I then retested on the 7th and they came back over 1800. The doctor said everything is doubling like it should. I have no clue when I ovulated other then what the app says but I feel I may be a week behind based off the HCG levels. I have had 2 missed miscarriages and 1 live birth with the miscarriages being before and after. I don't have a 8 week scan until the 28th but I am WAY more worried this round then I was with my son. I did have sore breast for a good 3 weeks and now that is subsiding and they now just feel "heavy" and I was peeing frequently but not sure if it was all the water I've been drinking and I have been tired with some dizziness but not terrible, super emotional hear and then there and have had strawberry cravings. I know all pregnancies are different but I was hoping to hear what everyone else experiences have been or something to ease my mind. Sending positive vibes to everyone!!
