Pregnancy?

Okay so I’m on birth control and all my siblings were born while my mom used several birth control methods at the same time. My first daughter is 7 months old and I am on birth control I took it late one day and now my stomach has started to hurt like during pregnancy number one. I am also getting nauseated after eating a meal and my arms will get week as well as getting dizzy. I also after having my daughter stop liking pickles all together and now I like them again. Could these signs be pointing to pregnancy. I wanted to also add that when ever I lay down I feel like there is a hint of pressure on my stomach and I haven’t ever felt like that before. I feel like I’m going crazy thinking that I’m pregnant again but I just don’t know.
