Hey there, I've been feeling dizziness,tiredness, breast tenderness and nausea. Anyways i took one depo shot and when it was time to get another one I went to see my obgyn. She told me it should be out of my system with in a month. Its been over a month now and I am feeling all these symptoms. I have been having unprotected sex all throughout this month and taken 5 hpt but there all neg. Even the obgyns was negative, could I still be pregnant? Should I get a blood test?
