You can take low dose aspirin during pregnancy, but you should only do so if your doctor has said it’s okay.
Daily low dose aspirin can even be recommended by doctors to help with some medical issues that can arise during pregnancy, including:
Heart attack
Stroke
Pre-eclampsia
If you’re having fertility treatment
If you have had several miscarriages
If you are pregnant, then you should avoid any medications that have not been recommended to you by your doctor or another health care professional.
This includes the standard dose of aspirin that is used for pain relief (300mg), which should only be taken if your doctor has advised it and should not be taken at all after 30 weeks of pregnancy.
