I have now been on the shot for about a year and I haven't been late not even once, plus my shot isn't due for another week. I last had sex about 2 weeks ago and I have been sick for about 1 1/2 weeks. I've had lots of belly pain, some smells make me sick and I feel like I want to throw up, I have heartburn, and im getting pains in my breast. I had a baby 2 1/2 years ago but I was never sick with my pregancy. I breast feed him for 6 months. But now since i've been feeling sick i'm getting milk out of my breast again... Is this normal or is it possible for me to be pregant?
