Hello and welcome to HCM
First of all I would suggest you to confirm pregnancy
by a pregnancy test.
If you have already got one done then you need to visit your gynaecologist.
At this point of time, pills commonly known as 'morning after pill' do not work. They are effective only within 72 hours of unprotected sex.
An IUCD insetion is also effective but within five days of unprotected sex.
Now the only option left is the medical termination of pregnancy and it is safe within first few weeks of pregnancy (you are within two weeks, so good time to get it done).
However, before getting it done ensure that your hemoglogin is good enough (atleast 11gm%)as you may bleed during the procedure.
Thanks and take care
