Weight loss?!

Dawn • Mama to Samuel Andrew Lee Borger💕 4-1-18💕

So far during this pregnancy I have lost weight around maybe 10 pounds?! I’ll be 19weeks on Monday. Is this normal?! My dr hasn’t really said anything but I noticed tonight that I now can’t wear my grandmas ring anymore due to losing weight and I have never taken it off in the 3yrs that I have had it
