Weird smell...garlic? phantom smells?

So this is odd but i figured I'd see if anyone has experienced this before. Last month I had a chemical pregnancy. During my 2 week wait I started smelling garlic. I thought I'd put too much in some spaghetti I'd made but it drove me nuts for a few days before I got my positive pregnancy test. This month, I'm again waiting to be able to take a test and suddenly smelling garlic again. It's not coming from me and seems to be my house/my 1 year old?

I don't understand this. I mopped and wiped down everything and then lit candles. I know it's not actually my house or my son. I googled and found some things about phantom smells during pregnancy. Anyone have this happen to them? I'm hoping this means I pregnant again!
