Negative; Estrogens and progesterone

Contraceptive pills mimic the negative feedback effect of estrogens and progesterone.

Explanation:

Estrogens and progesterone are regulated by negative feedback mechanisms, and therefore, birth control pills make use of this fact.Birth controls pills adds extra amount of estrogen and progesterone which inhibits the release of these hormones by the body.Consequently the release of an egg from the ovary is inhibited and the lining of the uterus is made to become thin and unsuitable for pregnancy by the absence of progesterone hence decrease the secretion of  the luteinizing hormone and the follicle stimulating hormone by negative feedback.This process ends up inhibiting ovulation.
