Pregnancy brain!

My husband does not believe this is a real thing, but I swear my brain does not remember things like it did before I was pregnant. For example, every time I look in our fridge I am surprised--I either find something I don't remember buying, or I don't remember eating something that's missing (and he didn't eat it so it had to be me). Also, yesterday I forgot to turn the oven off...all night. We found it this morning...oops. And tonight I mistook wax paper for parchment paper, which is not AT ALL the same thing. I almost set the kitchen on fire! Good grief. I am usually not this careless or dumb. Is anyone else struggling as much as I am??
