Not tasting spice?

So, I'm 7 weeks today, but as of about 5 weeks I've noticed that I can't really taste spicy foods any more. I'm not craving them specifically, but I just can't taste the flavor.

For example: I used to get pickled jalapenos on my Mexican food, and often would have to pick them off after a while because it would be too hot after eating just one or two. Now I get them, and I taste the pickle flavor and the pepper, but it doesn't taste hot at all. Other times spicy foods have been snuck into meals (added sriracha for example), and I didn't notice until my nose started running that it was probably hot, or until someone else said something about how hot it was.

Am I weird, or has any one else experienced this?
