I and my girlfriend had unprotected sex two months back. We took I pills daily. She had slight bleeding in that month. Next month she had bleeding and cramps just like a normal period, the bleeding was so heavy that she had to change 3 pads a day. Now she has white discharge with slight abdominal pain, nausea and back pain. Are these symptoms that she is pregnant? Is she pregnant? Was it her periods? Please help we are only 19.
