Re: strange pains
A bladder infection would give you an "ache" just above the pubic bone. I suspect the pains you are feeling are round ligament pains - caused by the ligaments attached to your uterus stretching as your uterus grows, and completely normal. At 9 weeks, you are right on time for these! They can sometimes be very very painful, but tend to come and go quickly. sometimes they hang around for a couple hours, tho.
If it continues to hang around, or gets worse, call your doctor ... that is what they are there for!
