I have been through two sessions of the Depo shot and have been experiencing my cycle since May. It is now Sept.and it has only stopped for about a week altogether. I have never missed a shot and have taken them in the time frame alloted. However, lately I have been experiencing this horrible pain that feels like contractions and the only way it goes away is if I go to sleep. Also, I feel this fluttering sensation in my stomach as if someone is in there. Is it possible for me to be pregnant? If so can I be pregnant while having an on going cycle, that breaks for no more than two or three days. The flow is never heavy its like a constant spotting. The symptoms of pregnancy that I experience are fatigue, constant urination,heart burn and excess gas.( Burping) Please help me.

While it is possible, this can also be side effects of the depo. Since you have been bleeding this long, I suggest you visit your doctor to discuss another form of birth control. Bleeding this long can cause anemia.
