So my girlfriend had a 10 day period last month, which ended on 30th and she was expecting this month's to come yesterday but it didn't, so she is a little worried, she is afraid of pregnancy, we take precautions every time wether as a condom or as contraceptive pill, still she is feeling like she has got pregnant as she has sore legs and getting period cramps kind of feeling but not getting any periods, I don't want to freak her out with a pregnancy testing kit if there's nothing or should she take a test? or this is just a delayed period dates issue.? Thank you.
