The endometrium would break down due to low hormone levels.
Estrogen in the system without the balancing effect of progesterone has been linked to an increased risk of endometrial cancer
The hormones that primarily regulate the menstrual cycle are estrogen and progesterone. Estrogen helps build up the uterine lining, while progesterone maintains it. Changes in the levels of these hormones throughout the menstrual cycle control ovulation and menstruation.
this urine linning is most responsive to the hormonal effect of strogen and progesterone ovaries.
Prolactin releasing factor
The active ingredients of the combined oral contraceptive pill are estrogen and progesterone. These pills are taken to prevent ovulation to prevent unwanted pregnancies. There is synergism between estrogen and progesterone where estrogen leads to progesterone receptors being upregulated so that they are more sensitive to progesterone. The combined oral contraceptive pill is highly effective. Its effect on preventing ovulation is the greatest. In addition to these effect, it can prevent unwanted pregnancies by thickening the cervical mucus, reducing the transport of the egg and the sperm in the Fallopian tubes, and changing the endometrium so that implantation is less likely to occur.
No Piriton allergy tablets do not affect the contraceptive pill. Antihistamines do not affect the effectiveness of the ingredients estrogen and progesterone in the birth control pill.
Unfortunately, there is very mixed data regarding hormones and heart palps. Dr. John Lee surmised that excessive estrogen ("estrogen dominance") caused heart palpitations and other vasomotor issues (hot flashes, night sweats, etc.) Other physicians state that excessive progesterone cause heart palpitations and that estrogen is a "feel good" hormone. Personally, I believe the answer is yes to your question due to my experience, but which hormone(s) is the big question.
prolactin releasing factor and testosterone/estrogen depending if it is male or female
Estrogen has a vasodilation action on blood vessels.
Your estrogen & testosterone will plummet & you will have full Menopausal symptoms.
Higher bone density
The exogenous progesterone effect, aka pill endometrium, occurs when a female takes a contraceptive consisting of progesterone. This causes a ripening of the endometrium consisting of increased stroma, plumping of cells (pseudodecidua), and edema. The major difference between this and the secretory phase is that the glands are small and atrophic because they lack a priming by estrogen, therefore the endometrium will break down regularly and you will get DUB (dysfunctional uterine bleeding).
