I had unprotected sex on 28-29 November and then took unwanted 72 and had mild bleeding on 4dec that lasted 4 days. My next period was supposed to come around 13dec.
Now its 14th January today and I haven't got my periods.
I did urine hcg test on 10th which was negative.. and then
beta hcg test on 13th Jan which showed 0.25.
Is there any chance of pregnancy and what can be the other reason of missed period ?
