Confused??

Shauna • Hello I`m Shauna 24 years old from NC. I`m new on here, I`ve been married for 3 years and have a beautiful daughter.
I just had a light period on November 27-30. I'm in my peak time now but I noticed I've been having some pregnancy symptoms. My boobs hurt, I've had crazy heartburn, some slight pains in my stomach, and increase in appetite. What is going on with me? Anyone go through this?
