Can symptoms start so long after a miscarriage?

I had a missed miscarriage when I was 7 weeks gone. I passed everything naturally with no complications over 2 weeks ago. While I was pregnant I had very few pregnancy symptoms and they all went the day before I miscarried, I felt like my normal non pregnant self. 14 days later I feel very pregnant like I did with my daughter, who is now 8. Can symptoms start so long after a miscarriage, I didn't feel like this when I was pregnant with the baby I lost?? So confused. I have had a follow up u/s and everything had passed and my uterus & lining were all normal. Any help would be appreciated. Thanks.x
