Play dough????

Okay so my husband is very in tune with my body. He can smell the change in my pheromones when I’m about to start and stop my periods, etc. Okay, so for the past two days he keeps saying “you smell like play dough.” I haven’t changed a single thing in my routine that would elicit that smell. I don’t smell it on myself. But I googled it because it was freaking me out and several moms have said that pregnant women smell like play dough??? This is so weird. I’ve also been peeing A TON more than usual, but I had my period two weeks ago and I’m not even supposed to ovulate until the first.....it’s way too soon to be pregnant....right????
