I'm in pain after my medical abortion

Feeling some discomfort is normal after having a medical abortion (or abortion pill). You'll have contraction type pain and cramping while you're passing the pregnancy. This can last for several hours or come and go over several days until the pregnancy is passed. Although many women pass the pregnancy in the first 24-48hrs, for some it can take up to two weeks.

After taking your second set of tablets

You'll experience bleeding and some cramping although this may not be happen straight away. It's very important you use pads and not tampons to avoid infection.
  • You'll be advised to take pain relief in the form of Paracetamol and/or Ibuprofen. You can apply a warm pad or (warm) hot water bottle to your abdomen if this makes you more comfortable. Please do not take Aspirin.
  • The cramps may get stronger - this is a normal part of the abortion process.
  • Bleeding may get heavier and you may pass clots. This is usually at the time that you'll begin to lose your pregnancy.
  • Often the pregnancy is passed into the toilet, you may not see it specifically, and this may appear as a clot.
  • Side effects of the medication may include nausea, vomiting, diarrhea and shivering. The onset of these symptoms can be fairly soon after taking the medication, so you need to plan your journey home. We recommend you are accompanied and are driven home.
  • Once the pregnancy has been passed, your bleeding will usually lessen and become like a slightly heavier period. It may continue to be quite heavy for a day or two as the uterus needs to contract and return to its normal size. If heavy bleeding occurs for more than two days, or you are soaking more than two pads per hour for two hours or more, please call our helpline for advice.
  • The abortion may take place within four to five hours and is usually completed within one to two days. Very occasionally, it can take up to two weeks to pass the pregnancy.

Pain relief

  • You'll be given advice on pain relief tablets such as paracetamol, codeine, or ibuprofen. These pain medications will not interfere with the abortion medication. We recommend you buy some Ibuprofen and some Paracetamol, or Paracetamol with codeine. You can take Ibuprofen or Naproxen but not both together. If you need more pain relief, you can take Parecetamol with either Ibuprofen or Naproxen. 
  • Please do not take aspirin as it can increase bleeding.
  • You can apply a heat pad or (warm) hot water bottle wrapped in a towel or blanket to your lower abdomen if this makes you more comfortable.
  • Comfy, loose clothes and being comfortable and relaxed at home can also lessen pain

Serious complications have warning signs.

If you experience any of the symptoms below call us straight away: 

  • Very heavy bleeding that soaks through more than 2 sanitary pads an hour. 
  • Abdominal pain or discomfort that is not helped by pain relief medication, or by heat pad.
  • Vaginal discharge that smells unpleasant.
  • Feeling hot and shivery with a high temperature of 38°C or more.
  • Morning sickness that continues for seven days following the abortion.
  • Bleeding has not started 48 hours after inserting the tablets into your vagina.
