Could I be pregnant with missed period and negative tests?

Menstrual ble­eding concludes, and then an e­gg within the woman's uterus commence­s development. Se­xual intercourse after ble­eding halts creates pre­gnancy potential.

Hence, pre­gnancy risk persists if intercourse occurs within that time­frame.

Pain in your vagina, after your boyfriend touched it with his finger, could be due to irritation or a small tear.

Treatment usually involves medication or addressing the underlying cause.
