Hormonal types of oral contraception can successfully prevent pregnancy, provided that they are taken properly, with the user following the instructions correctly.
As far as Australia is concerned, there are two possible choices when it comes to these means of contraception. Basically, there are two combined pill variants and single pill ones. Both of these pills are obtainable from any pharmacy. Yet, before getting the pills, you need to have a prescription for them, issued by a doctor.
The Combined Pill
As it was mentioned above, the first type of oral contraception is the combined pill. This pill type functions through preventing the release of the egg, which is the process otherwise known as ovulation. Also, this type of contraception makes the lining on the entrance to the womb thicker, preventing sperm from passing it with ease. Additionally, the changes on the wall of the uterus that these pills trigger make it impossible for the fertilized egg to stick to it.
Thus, this type of protection from pregnancy is effective in about 99.7 cases, once it is used properly. The dosage of the pills may be fixed, or may be different, depending on the time of the menstrual cycle. Also, the levels and the presence of estrogen and progesterone in the pills may vary.
These pills come in packs of 21 or 28. While the latter type provides pills which are taken every day until the menstruation, the former one involves making a 7-day pause. However, the 28-packs have up to 7 sugar pills which do not have any contraceptive capabilities but, rather, prevent one from losing count or skipping a dose.
Pros and Cons of the Combined Pill
The positive sides of the combined pill are less complicated and painful periods, reduced risks of cancer affecting the ovaries or the uterus, control over your periods and a successful treatment of acne, if the user has any.
However, the necessity of remembering to take the pill everyday may be bothersome for some women. Also, the pills are quite costly, involving you to visit your doctor before purchasing every new pack, which is considered to be a drawback for many. Finally, side-effects like nausea and headaches, combined with the danger of developing some serious health conditions like heart attacks or deep vein thrombosis, cause these pills to be refused by many individuals.
The Mini Pill
The mini pill is yet another alternative, protecting a woman from pregnancy by thickening the lining on the cervix, preventing the sperm from passing through. Again, if taken properly, this pill is up to 99.7% effective.
This pill contains only progesterone, being an excellent alternative for women who cannot take estrogen-based contraception. Also, this pill does not interfere with breastfeeding.
Yet, it may cause abnormal bleeding, diarrhea or vomiting, increasing one's chances of developing cancer.
Finally, none of oral contraceptive pills protect women from sexually transmitted diseases.
