Is constipation supposed to let up? (Tmi)

I'm about 11 weeks and lately I've noticed that I've been able to have a BM a few times a day (whereas before it was once every other day). I should say that I have eaten quite a bit of triscuits (fiber) and drank a bit of apple juice, but I'm just afraid that it means I am going to miscarry. I want to see a doctor, but my appt isn't until the second week of feb. :(
