Baby number two

Three years ago I had my first son Elijah by C-Section. Five weeks later, I had to removed my gallbladder. I got on birth control to be able to heal probably. Got off the birth control when he turned one. Ever since we have been trying. I missed my period this weekend so I decided to do a pregnancy test. My son had told me a week before my period that I had a baby in my stomach but he’s three what dose he know. The result from the pregnancy test is : of course I had to do multiple.
