7dpo (nearly 8) and smell aversion

Aislin
I know 7dpo is very early for symptoms (although I was only 8dpo last pregnancy when I started feeling weak and nauseous which lasted until the miscarriage, with taste and smell aversions well underway by the time the digital test turned positive at 16dpo) and I'm trying not to get TOO excited but my sister's wellies STINK. Not her feet, but the actual material, the PVC stuff they make wellies out of.
She sat next to me and after a few minutes I had to make her take them off and put them in the cupboard. She thought it was hilarious and everyone agreed that they smelled when they took them and sniffed (again the boot, not the inside of it) but nobody could smell it from just being sat near her (even my sister with her pregnancy nose). Went to get my coat from the same cupboard a half an hour later and the smell hit me in the face the second I opened the door. It's disgusting, like melted plastic or burnt rubber. 
Hoping this is my month!
