Hii am 22years old, on feb 8 me and my boyfrnd had gone for picnic he rubbed his pennis on the top of my pussy. He said that he didin't had any sperm but iam tensed and taken premolut-n tablets 2 per day for 5 days and got periods after 4 days that is on feb 19. Bleeding was normal a bit heavy too like my normal periods but only lasted for 4 days. After my periods that is from the 5th day iam having white milky discharge, back pain, head ache and discomfort in my stomach. I don't know whether it is my psychological feeling or else but iam very tensed. Am i pregnant? please help me.
