What are the most common causes of right lower quadrant pain in pregnancy?
Any of the conditions already mentioned can cause pain in the right lower quadrant (RLQ) whether you are pregnant or not, so you should always get checked out.
- Constipation is very common in pregnancy.
- It gives you crampy lower tummy (lower abdominal) pains.
- You will open your bowels less often than you usually do and typically you pass hard, pellet-like stools (faeces).
Pelvic ligament pain
- Typically this starts around 14 weeks and goes on into late pregnancy.
- It is due to the growing womb (uterus) pulling on the structures (round ligaments and broad ligament) which hold it in place.
- Usually causes a stabbing pain down one or both sides of the tummy (abdomen) and sometimes down into the hips and genital area.
- Pain can be quite marked.
- Urine infection is more common in pregnancy.
- Usual symptoms are of pain when you pass urine and passing urine more often.
- You may also get tummy pain and a high temperature (fever) and notice blood in your pee.
- If you do get pain, it's usually across the lower tummy but can be on one side if you are developing a kidney infection (pyelonephritis).
- An ectopic pregnancy is a pregnancy that is not in the normal place.
- Pain is often sudden and can be severe, but it can come on over a few days.
- You may have missed your period but you can still have an ectopic pregnancy even if you think you have had a period.
- Vaginal bleeding often happens but not always.
- Occasionally you can get pain over the tip of your shoulder.
Right lower quadrant pain in later pregnancy
In later pregnancy, RLQ pain can be caused by a placental abruption or by going into labour. Placental abruption happens when there is bleeding between the afterbirth (placenta) and the lining of the womb. Labour is too soon (premature labour) if it happens before 37 weeks.
