Hi I had protected sex with my girlfriend at 21and 22th April. She used to have her period on 11-15th.. but she missed her period.. on the 22th april less than 7 sec we had sex without condom but I didn't ejaculate inside her.. from 28th-29th April she used to have white discharge.. and from yesterday she is having a small amout of blood flowing from her vagina.. I just want to know if she is pregnant or is she is starting to have her periods?
