So, if I understand this correctly, you want to know if having sexual intercourse for the first time on the day before your period is due could delay the onset of your period?
Stress or anxiety can delay your period (or bring it forward), so if you found the experience stressful, it could do by a few days or so. It is, of course, possible to get pregnant the first time you have sex, if protection is not used. This is much less likely at the end of the menstrual cycle, i.E. Just before the period, but it is still possible. So, in that sense, your period could end up being delayed by 9 months.
The second part of your question doesn't really make any sense. There is nothing to "heal" after becoming sexually active. The hymen may break the first time one has sex, hence some bleeding, but many women will already have ruptured this through sport or physical activity before having sex for the first time. In any case, this does not "heal" in any meaningful way.
i am a virgin. but when my bf fingered me a few nights ago it really hurt at the end. and a few hours later( about 5 hours ) i was bleeding but only a little bit and never bled after that. did i pop my cherry? or am i on my period? or something else? because i dont know if you can bleed few hours later after popping the cherry. please help!
My Girlfriend Fingered Me (Im A Complete Virgan I've Never Had Any Type Of Sexual Anything Until Her) And I Bleed A Lot About 20min Later. The Next Day I Bleed Also Bt Its Not As Red As It Usually Is When I Start My Period What Happened? Did She Pop My Cherry?
I'm freaking out I did it for the first time on the 26 we used protection he mostly fingered me and when he put it in it was less than a minute and with protection he did pop my cheery but my period is at the end of the month we did it the 26 I'm scared could I be prego? Should I be worried
