I've been doing strength training for over a year, which is why I'm confused by the change all of a sudden. I switch my strength training program every six weeks. And I've noticed this moreso in the past month, so I don't think it has to do with my menstrual cycle.

If you recently started strength training, what you're experiencing isn't unusual. When a person works their muscles intensely, their muscle fibers soak up water like a sponge. This is what they are supposed to do. You may even notice some swelling. Your muscles will release any excess water they don't need once they've adapted to the new exercise routine. And that could take a few days.
Not to get TMI, but are you nearing TOM ? Pants that are normally lose tend to get tight whenever a women is experiencing their menstrual cycle. That bloating can not only cause a woman's weight to increase, but cause pants to get tight too. That too is temporary.
Can you be gaining muscle ? How long have you been engaged in any strength training ? Have you been eating a surplus of calories ? If this increase is recent, it may be nothing more than a temporary water weight gain. It takes women an awful long time to pack on muscle.
How long have your pants been tight? If only a few days, it could easily be something you ate (artichokes make me go up 2 pants sizes!) or a menstrual cycle thing. When I'm not watching what I eat, I never gain or get bloated at any time during my cycle but if I am watching what I eat, I always gain several pounds and go up a size about 3 days before my period starts until about a day after it ends. It could just be something like that.
If this is something that's gone on for several weeks or longer, probably what MPLANE37 said. Sometimes our bodies change composition a little, but it would be pretty odd to put on so much muscle in your lower body that you'd feel it in your clothes.

Apparently something has changed in your body. It could be positive or negative, no one can know without getting your body fat % tested and comparing it to the earlier values. Even if you don't know the earlier body fat % values, now is the time to start monitoring it.
My wild guess is that if you have been doing the same exercises and have become very fit, you may be not burning as much as before. Try increasing the intensity.

I haven't changed anything in my diet...I get enough food, but I don't go over my calories. I exercise 4-5x a week consistently...but now all of my pants are starting to get tight. I normally do chalean extreme and turbo jam/turbo fire.
