10 wks dull pain in right side of stomach

I work on my feet all day filing, shredding, organizing, etc., and I noticed today that while filing I had a dull pain on the right side of my stomach. Is this normal? I’ve had one successful birth & 3 miscarriages. This is my second pregnancy and so far no bleeding, or vaginal changes. The pain wasn’t unbearable but I noticed it was there. Could it be just everything stretching out? I don’t remember having this pain with my first... I won’t have an appt until next wk with my midwife
