<s>[INST] Hi there, Im a 25yr old female with 3 kids. I just had a sharp pain slighty to one side in my lower abdomen. about 5-10 mins later I started bleeding bright red. Im not really hurting anymore, maybe a little ache? but Im not sure if I should call my doctor or what. Should I be looking out for any signs that turn this into an emergency? Im currently on the mini pill and im not due to start my cycle till around the 20th. What could this be?   ~HC [/INST] Welcome to Chat Doctor!. First thing you can suspect in this case is pregnancy with missed abortion.2. Get an UPT - urine pregnancy test to rule out pregnancy.3. As you mentioned taking mini pill - there are possibilities of failure. 4. The next possible cause could be hormonal imbalance.5. Get and appointment with specialist to get an ultrasound pelvis to evaluate uterus and ovaries in detail. Hope it will help. Do not hesitate to ask if any. </s>
