I Am Pregnant

All through my pregnancy, I have smelled strange scents no one else has been able to smell, they come from nowhere. I don't remember doing that when I was pregnant with my son, I have smelled odors like glue, wintergreen, etc at various times with no source of the smell around. I also didn't have food cravings with this pregnancy like you normally would expect so I am wondering if the weird scents I am picking up are a substitute for not having cravings. 🤔
