I had taken the morning after pill 3 weeks ago after having unprotected sex with my boyfriend..and after my period had arrived i decided to go on the pill on the Tuesday my period started. However I was having protected sex on the Wednesday night but the condom split. I was then drinking on the thursday and had forgotten to take my pill and had unprotected sex several times that night,although he did pull out before he came. It is now the following Thursday and I am still lightly bleeding and having really bad unbearable cramps along with headaches and dizziness..could I be pregnant ? I am also aware of how irresponsible I have been and would like positive feedback and advice as opposed to negative.
