Period pain, but no periods: what are the causes?

However, there are several reasons why you might be experiencing this. 

Here, we take a look at what some of these might be, providing some answers and support to put your mind at ease. (But, if your symptoms are painful and you're concerned, make sure you speak to your GP.)

Throughout your monthly menstrual cycle, the lining of your uterus builds up in preparation for a potential newly fertilised egg to implant.² Menstrual cramps happen when there’s a rise in hormone-like chemicals called prostaglandins, which trigger your uterus (womb) to contract and shed this built-up lining. These contractions are the cause of the discomfort you feel in the days leading up to and during your period.

If you track your monthly cycle – on a calendar or with an app, for example – you can get a rough idea of when your most painful days will be. For most people, the worst day will be the day their period starts, with the pain gradually easing during their period.³

In this case, the pain you feel may be especially bad in the days before your period starts, as well as during your period. It can also get worse, rather than improve, as your period goes on.^{3, 4}

Some of the conditions that can cause this type of painful period include: ⁴

It’s important to speak to your doctor if you think you may have a condition which is causing you severe period pain.

Some women will experience pain when an egg is released from an ovary, which can last for a few minutes, or up to 48 hours. When experiencing ovulation pain, it typically only affects one side of your tummy and causes either a dull ache or a sharp, sudden pinch-like pain.

The pain can also feel similar to period pain, and can sometimes cause light spotting, so the two can be easily confused.^6,7

The condition can also cause extreme pelvic pain on days outside of your period, pain during or after sex, and pain or discomfort when going to the toilet.^8,10

Symptoms of PCOS include difficulty getting pregnant, excessive hair growth, and irregular or absent periods.¹¹ 

Research shows that the irregularity of periods in people with PCOS can cause a much heavier bleed, which can result in more intense and painful cramping. This cramping may be severe and can start a few days before your period and last for a few days after you’ve finished bleeding.¹²

So, if you’ve been cramping for a few days, and your period is overdue, it could be because you’re expecting. 

You can take an at-home pregnancy test on or after the day your period is due to find out. Some tests you can purchase are sensitive to hCG (the hormone that indicates pregnancy) up to six days before your missed period.

In some cases, cramping and pain can be a sign that something is wrong. It can also be a sign that your contractions have started and your baby is ready to come into the world.¹⁵
