Many infertile women are confused about irregular periods. They need to understand that regular periods by themselves do not ensure successful conception.
Irregular periods are common in infertile women. However, many women are very confused about the relation between irregular periods and their infertility. They naively assume that once their periods become regular, they will conceive.
While it's easy to make the periods regular by putting a woman on birth control pills, this will obviously not help her to get pregnant.
You need to remember that just like infertility is only a symptom, and not a diagnosis, irregular periods are also just a symptom of an underlying problem called anovulation, or not ovulating. It is the underlying anovulation which causes both the irregular periods and the infertility, and this is what needs to be treated.
Infertile women with irregular periods need the following medical tests: blood test for measuring the level of the reproductive hormones, FSH,LH,PRL and TSH on Day 3 of their cycle, so we can find out what the reason for the anovulation is.
Once we know what the problem is, then we can treat it by inducing ovulation !
