Hi, I need help in this understanding.
My menstruation started on 12 Oct 2010 and ended 18th Oct (Not completely zero).
I had sex with my bf last night on 18th Oct and he eject inside me.
My menstruation has been irregular since I started puberty.. 1 month once, 2months once or 3 months once (Unpredictable)..
How high is the possibility of pregnancy?
If I am to test, when can I start to test?
