Does losing your virginity delay your period? I m 17 years old (female) and I had sex for the first time. We used a condom, I should be getting my period in about a week. I just don t want to freak out when I don t get my period. So, I m wondering, because it was my first time, could my body delay my period?I have test the preganct test in a medicine shopand it was negative but i have doubt.Can you please tell me about this?
