Why Your Period is Irregular After Fertility Injections

Infertility is a major problem for couples around the globe. Getting pregnant is not always as easy as it appears, although medical technology has made great strides towards helping couples conceive. Fertility treatments are a growing trend as more and more people attempt to have children, although treatments do have their downside. Many women have difficulty maintaining a regular menstrual cycle during fertility treatments, but this does not make conception an impossible feat.


Infertility affects an average of ten to fifteen percent of the global population. Numerous couples are waiting longer to have children, and the older a woman is, the more difficult conception is. Fertility drugs are administered to aid in conceiving, but often cause a disruption in the menstrual cycle. It is vital that those trying to conceive know when ovulation occurs, and an irregular cycle can make this difficult. A woman is most fertile during a brief window before and after ovulation, and missing out on this window often results in more heartache and disappointment.


Fertility drugs are normally composed of elevated levels of hormones injected directly into the body. These hormones, including gonadotropin-releasing hormones, stimulate the hypothalamus, resulting in increased ovulation. Others such as progesterone, help to maintain a normal cycle and retain pregnancy. Fertility treatments are given in conjunction with a woman’s menstrual cycle and can be used as often as her physician sees fit. These treatments are commonly given in the form of injection, lozenge, or suppository.


People often assume that just because a woman is on fertility drugs that her menstrual cycle will be very regular. The hormones in most fertility drugs cause the body to adjust itself and start the menstrual cycle over again, making it extremely difficult monitor ovulation. Many assume that simply because a woman’s cycle is irregular that she cannot conceive at all. Irregular cycles do make conception more difficult since it makes pinpointing ovulation a challenge, but many women with irregular cycles due to infertility still conceive and carry a baby full term.

Even with the trouble of an irregular cycle due to fertility treatments, a woman can still conceive. Women taking fertility treatments have a much higher success rate of pregnancy than those who attempt conception without them. Success rates as high as 50% to 60% have been noted in certain infertility cases with close patient monitoring.


Any woman considering fertility treatments should only do so as a last resort. Fertility drugs must be taken on a very specific cycle and at regular intervals. Missing a dose can render the drugs virtually useless. Fertility treatments are also very costly and not covered by a number of insurance companies. One course of treatment can easily cost over $10,000. Women taking fertility medication also need to attend every doctor’s appointment on schedule to assure they get the most accurate course of treatment for their infertility. Missing a checkup can be disastrous since hormone levels need to be closely tracked during fertility treatments.
