did anyone notice any differences between their miscarriage pregnancy and their rainbow pregnancy

Mr
Firstly sorry if I upset or offend anyone with this topic I just can't see anything else about this on the web. I have a 4 year old and I suffered a missed miscarriage earlier in the year and I just wondered if you knew the pregnancy was different even before a miscarriage occurred? I think I did because my second pregnancy only made it to 9 weeks but it was often a very dull ache in my left side and I can remember having at least 4/5 occasions where the pain was sharp. I also had stages where I had no symptoms and then days when I was. Again sorry if this post offends love to all.
