I haven't had a period for 3 months now and I keep needing the toilet more and also I keep getting headaches and 3 months ago I got fingered by a boy and he was wanking at the same time and he could have got on hishand and then put his fingers up me and he was fingering me hard and going up far... also my periods are usually regular??

Could I be pregnant??

Do you think I should see a doctor because I haven't had a period for 3 months any way

You need to go to a doctor and get a complete physical. There might be other things going on especially if your period is normally regular. Please make an appointment and get counseling through your medical doctor.
