Missing a period can be very difficult for infertile women ! Every time you miss a period, you hope ( against hope) that maybe you are finally pregnant! However, you are worried about getting your hopes up too high, because you are scared that they will come dashing down again - and you remember all the false alarms you have had in the past!
There are many reasons for missing a period, including:
If you miss three menstrual periods in a row, your doctor will make the diagnosis of "secondary amenorrhea ". This is just medical jargon for - " has missed more than three menstrual periods". It's not really a diagnosis - just a description of your problem.
So what are the reasons for a missed period? And what can you do about this?
Let's review some basic biology first. The reason women who ovulate get a natural menstrual period is because of a drop in the circulating blood levels of the reproductive hormones, estrogen and progesterone hormones. When these levels drop, the uterine lining loses its hormonal support, as a result of which it is shed as a menstrual period. This is called an estrogen primed progesterone withdrawal bleed.

A missed period means there is a problem with the normal balance between estrogen and progesterone in your body. This usually happens when you do not ovulate. This is called anovulation.
In order to come to the right diagnosis, the doctor may need to do a vaginal ultrasound scan. This should check for the following.
It's also possible to confirm this diagnosis by checking the blood levels of estrogen and progesterone.After making a diagnosis, it's easy to induce a period, based on the problem.
A thick endometrium
If the uterine lining ( endometrium) is thick, this means that the level of estrogen in the body is already high ; and it's easy to induce a period by taking 5 days of progestins, such as medroxyprogesterone acetate. There are many options available.
These include:Tab Provera ( medroxyprogesterone acetate), 10 mg, twice a day. The period will usually start 3-7 days after taking the last tablet. This is called inducing a withdrawal bleed with progestins.
For low estrogen levels
On the other hand, in women with low estrogen levels who have a thin uterine lining, we first need to build up the lining with estrogens and then induce a period with progesterone . We give the estrogen and progesterone hormones sequentially, thus mimicking a natural cycle. This is what a typical prescription would look like.
Estrogen tablets from Day 1 - Day 25. There are many options available. The least expensive is Tab Ethinyl estradiol ( Lynoral), 0.05 mg daily. Other choices include: Tab Premarin, 1.25 mg daily; or
Tab Progynova ( estradiol valerate, 2 mg), 2 tab daily. You may feel some nausea and have some temporary fluid retention while taking the estrogen.
Progestin tablets, from Day 16 - Day 25. There are many options available. These include:Tab Provera ( medroxyprogesterone acetate), 10 mg, twice a day.
This regimen is called Hormone Replacement Therapy , and is available commercially in some countries in the form of a pack, called CycloProgynova. The withdrawal period ( menstrual period) will start approximately 3-6 days after you take the last tablet, as the levels of the administered hormones decline in your body because they get excreted in the urine.
It's also possible to achieve the same results with a 21 day course of birth control pills, since these contain both estrogen and progesterone. It's best to take the old-fashioned monophasic birth control pills, which contain a sufficient amount of estrogen and progestins ( combined together in one "active" tablet).
A typical choice would be Ovral, which contains 50 ug of ethinyl estradiol and 500 ug of norgestrel ( a type of progestin). The withdrawal bleeding induced when you take birth control pills may be scanty as compared to a regular period. This is normal.
If the reason for the missed period is a functional cyst, you may have to wait till it resolves. It will usually do so on its own. If needed, the doctor can induce a period with mifegest ( RU-486), a very powerful antiprogestin.
