I recently took my second dose of the Depo Shot (Jan 17) and I have been having some stomach pains. It hurts to lay on my stomach or on my right side. I never really noticed any pains until about a week or so before. I had a pregnancy scare in November but it came out negative and I don’t go to the doctor for my shot. Is there anyway I could be pregnant and not know it? Some women don’t produce enough of the pregnancy hormone to get a positive. If I am pregnant I would be around 12-13 weeks.
