Hi ! Good evening. I am Dr Shareef answering your query. If I were your doctor, I would advise you for a blood CBC, serum HCG specially if your are sexually active followed by an ultrasound to rule out a leaking ectopic pregnancy giving rise to fluid in the abdomen. This could be decided by a clinical examination of the abdomen along with the reports of investigations as noted above. Further management would depend after confirming the diagnosis. However, if you get another fainting attack later, I would advise you to visit the ER of a nearest hospital instead waiting for your turn to come for the gynaecologist. I hope this information would help you in discussing with your family physician/treating doctor in further management of your problem. Please do not hesitate to ask in case of any further doubts. Thanks for choosing health care magic to clear doubts on your health problems. I wish you an early recovery. Dr Shareef.
