Its been nearly 1 month since she had her last period. We came close physically nearly just after her last period was over. I didnt penetrate her. Very rarely but she sometimes feel to like vomiting but never did it though. So is there any chance of pregnancy? If no why the period is beign so much delayed (her periods were irregular but for past 2 or 3 months it was regular)? If yes then what should we do now? We don't want a kid now. We are nervous and getting afraid day by day. So we need some suggestions and help.
