Hi,

My periods are irreuglar. I had my last period on the 23rd Dec to 27th Dec. During 7th jan, i had unprotected sex with a pull out method. I didn't have any symptom of pregnancy at all. But yesterday, my period suddenly came (I dont think,it's an implantation bleeding) and filled up my pad. It was really heavy and as well as today. 

 

Do you think i am pregnant? Thank you for any response!
