Uhm.. My menstration is irregular... in previous months, i had my period with a little blood.. and I don't have sex. So, I know that my menstration isn't normal.. well, last oct. 3, 2012.. I have my period.. this time, a lot of blood came off. then in the 6th day of my period, my boyfriend and I had sex and he ejaculated inside me.. in the evening, a lot of blood came out... so i think that the sperm had died... a week later, i am seeing blood spots in my underwear for about 3-4 days every night.. I am supposed to have my period last Nov. 3, 2012.. but it did not came... Am I pregnant?
