Saddle Issues

I would also think it could very well have to do with the fact that you're pregnant - depending on how far along you are. Your bones will move/spread so that you can give birth The baby could also be sitting low and putting additional pressure on you from the inside, thereby compressing your sit bones further.
If the saddle worked before, and isn't worn out, I'd guess it has to do with your body changes. If you want to ride while pregnant, a different saddle might help if you give that a try, If it doesn't matter right, especially entering the second half of your pregnancy, maybe just wait until you start riding again after you have the baby - I'm sure you've got plenty of other things you could be spending money to prepare for your new arrival rather than a new saddle!!!

I wonder how a brooks saddle would hold up to pregnancy. If you were riding it throughout, maybe the leather would change with you. But if you had a hiatus, say for winter or morning sickness, the leather would be all wrong.

Good luck with the saddle issue, I hope it is just that you aren't accustomed to it. I'm sure Mr. Fanatizarre will go along with the need for a new saddle temporarily if necessary.

Melalvai, the leather just doesn't change that much, and neither do your bones. I don't see how using a leather saddle during pregnancy would be a problem.
I think JennK13 is right on though... maybe after you have the baby, the saddle you have will be just fine.
