Is this normal?

I am 15 weeks along and have been getting sharp pains in my lower abdomen when I roll over in bed, sneeze, cough, or especially when I stand up. This has been going o the whole time I've been prego but are getting worse recently. Is it my belly stretching? I don't have a baby bump yet.
