Thanks for the query.
Some amount pain abdomen can be seen during pregnancy
Which can occur due to growing of the uterus
If the pain continues you consult gynecologist once and get examined for:
-To rule out urinary tract
-Any possibility of uterine action
If needed you can go for progesterone
supplementation with your doctor's advice.
