So I have been off Depo Provera for about 5 months and I have had a boyfriend since then and have casually had unprotected sex.. I have been on Birth control since I was 15 and Ill be 19 this year, so I figured chances of pregnancy is very low? I have taken three tests all have said negative, but I HEAVILY am experiencing the symptoms.. I dont want to be psyching myself out, but I have looked up other responses from ladies off the depo and they said even after 10 years in some they got pregnant as soon as two months after
