Pelvic pain outside of your period: what can it mean?

Pelvic pain outside of your period can come from ovulation, a cyst, an infection, the bowel or bladder, or endometriosis. What points the way is when in the cycle it happens and what comes with it. Sudden, severe pain, or pain with fever, means seeing someone the same day.

First: where are you in your cycle?

That is the question that guides everything. Pain on one side of the lower abdomen, around mid-cycle, lasting from a few minutes to one or two days, is very often ovulation pain. It is ordinary and harmless.

Pain in the days before your period is, for many women, part of premenstrual syndrome.

Pain with no link to the cycle, that comes back at any time, or that settles in, tells a different story.

The common causes

Ovulation. Pain on one side, mid-cycle, brief.
An ovarian cyst. Common and most often benign. It can pull on one side for several weeks. It shows on an ultrasound.
Endometriosis. Pelvic pain outside of periods, often with very painful periods, pain during sex, pain when passing stools or urinating during your period, a bloated belly, exhaustion after your period. This is the lead to raise when the pain repeats and ruins daily life.
Adenomyosis. A cousin of endometriosis, in the muscle of the uterus. Heavy, painful periods, pelvic pain.
An infection. Pain with fever, unusual discharge, burning when urinating.
The bowel or bladder. The lower abdomen does not only contain the uterus. Constipation, irritable bowel syndrome, cystitis cause very similar pain.

What to log so the appointment is useful

Doctors always ask the same questions, and they are hard to answer from memory. For each episode, log:

the day of the cycle;
the side, the intensity from 0 to 10, the duration;
what comes with it: bleeding, fever, discharge, digestive or urinary symptoms;
whether it happens during sex.

Over two or three cycles, that notebook is worth more than a long story. Lovae has a section dedicated to endometriosis symptoms, precisely so that this information does not get lost.

When to see someone

The same day, or at the emergency department:

sudden, intense pain, especially on one side;
pain with fever;
pain with unusual bleeding, if pregnancy is possible;
vomiting, feeling faint.

Not urgent, but without waiting:

pain that comes back every cycle outside of your period;
periods so painful that they stop you working or going out;
pain during sex;
pain that has lasted more than three months.

Lovae is a wellbeing app, not a medical device. It helps you document your pain; it does not explain it for you.
