Started Omeprazole

Ive started taking Omeprazole little over and a week and ive had a alot of side effects nauesa etc.I had my blood work done cbc ferrin lft etc but the doctor wants to run a white blood count again in 2 weeks does Omeprazole mess with blood work?

It can cause osteoporosis.  I took it for over 10 yrs and had horrible side effects when I decided to get off.
