hello, i am Raihan... last month on 26th april me and my girlfriend had sex. i was sure that my ejaculation was happened outside not in her vagina. though she was a virgin i had hardships to perform, and if some of my sperm adheres to her vulva (i am little sure about this) so does it have possibility of getting pregnant? we didnt use protection or pills. today 12 days left. she told me that her breast size is changed but everything is quite okay, no other symptoms. and her period was not regular but she had her period 7 days after normal time...So what should I do now? test her pregnancy? how? i was sure my sperm did not went through her vagina, but sometimes i become scared. i need advice
