What is ovulation pain?
Ovulation pain happens when women feel pain in their lower tummy (abdomen) during ovulation (when an egg is released from an ovary during your menstrual cycle).
This ovulation pain is also known as ‘mittelschmerz’ (the German word for ‘middle pain’ or ‘pain in the middle of the month’). This pain is usually normal and nothing to worry about, with around 4 in 10 women experiencing it.
What does ovulation pain feel like?
Ovulation pain is usually felt on either the left- or right-hand side of your tummy depending on which ovary is releasing the egg. The sensation varies widely between people, ranging from feeling a mild twinge to experiencing very severe pain. It can last a few minutes to 1 or 2 days. For most people it’s present for between 3 to 12 hours.
It usually happens about 2 weeks before youris due, and can either switch from one side of your tummy to the other from one period cycle to the next, or remain on the same side for a few cycles.
What causes mittelschmerz?
The exact cause of ovulation pain isn’t clear, but it’s likely to be caused by one or both of these causes:
- pain due to the growth of a follicle (a fluid-filled sac in which an egg develops) – your hormones prompt your ovaries to produce follicles, with each follicle containing an immature egg (ovum). However, only 1 follicle usually survives to maturity, and it’s thought that mittelschmerz can be caused by the expanding follicle stretching the external covering (membrane) of the ovary
- pain due to a follicle bursting – when your egg is mature, it bursts from the follicle and, along with slight bleeding, this may irritate your tummy lining (peritoneum) and trigger pain
How to treat ovulation pain
Most people find they don’t need specific treatment for mittelschmerz as it goes away fairly quickly. However, if it doesn’t go away and you need treatment, try:
- taking simple such as paracetamol or simple such as ibuprofen – but first speak to a doctor or pharmacist about how to safely get and use these medicines. And if you’re trying to get pregnant, don’t take them as they can interfere with ovulation
- applying warmth to your lower tummy – use a heat pack or hot water bottle wrapped in a towel, or have a soak in a hot bath to relieve the pain
- taking the – this can help prevent ovulation pain because it stops ovulation. If this is something you’d like to consider, discuss it with a doctor
