I got my last depo shot on August 19 and had unprotected sex on October 3rd. He pulled out before he "came". I've been on the depo shot for around a year, but since we did have unprotected sex other than my depo shot, I'm nervous I could be pregnant. I've taken multiple tests and they all say negative but it has only been about a week and a half. My stomach always hurts so I'm unsure if it's my digestive track of if I'm pregnant.. I really don't want to be pregnant and I've been stressing out about it ever sense. I wake up randomly at 4 am and cannot go back to bed I get so nervous. What are my chances of being pregnant?
