Hello, I would be happy to help you with your question.

What you are describing is "anovulatory cycling". Mid-cycle, women ovulate (produce and egg). If the egg is not fertilized, then there is a predictable withdrawl bleed afterwards. In your case, there is obviously extreme variation in terms of when you ovulate.

In some cases, women who do not ovulate do not get a period. In this case, they sometimes need medication to "start" a period. This is what they did in your case, which worked, but now you have fallen back into an anovulatory pattern.

It sounds like they did testing that was "normal" and should have included tests for thyroid disease, diabetes, and measurement of a hormone called prolactin (at the least).

If you are not trying to get pregnant, then birth control pills are most often used to regulate your cycle. If you are trying to get pregnant, then medications to force ovulation are used (one is called clomid).

I am hoping this answers your question. If it does, make sure that you accept and review the question so that I can get feedback from you! If you have more questions, please ask!!

In the workup of anovulatory bleeding you need:

1. TSH, free T4 and free T3
2. Prolactin
3. Fasting glucose, fasting insulin (your doctor can interpret the ratio of these two)
4. An ultrasound to look at your ovaries and uterus
5. LH, total testosterone, and DHEAS

I hope this helps, please provide feedback! Good luck!

No, this can be performed at any point during your cycle. Ideally, the prolactin level would be checked fasting.
