Hello, thanks for using Chat Doctor Pill is a progesterone based medication and it is effective IIN preventing pregnancy when taken within the recommended time period of less than 72 hours following intercourse. Ipill being a progesterone, has the potential of altering menstrual flow both by volume and duration. However, this is just temporally and gets regularized after a couple of cycles. Occasional in take of Pill has no effect on fertility. However, persistent in take for years could suppress ovulation that would take a long time say up to six months and even above one year before coming back. With absence of ovulation, you will definitely be unable to get a pregnancy. Unprotected intercourse is a risk factor for sexually transmissible infections such as HIV, herpes,, hepatitis B virus and HPV which is associated with cervical cancer. Hope this helps you. Best regards Chat Doctor.
