Hi. Recently, about on 20th of April, me and my partner indulged in a sexual act, but I had not used and physical contraception; although I had retracted before ejaculation. Somehow, it's roughly been about a month, and she has not gotten her periods. No abdominal paid, no vomiting, no indications of periods, or upcoming periods. Could you tell me as to how to go about this, and even before that, how to check if everything is alright, and she has not gotten pregnant.
