My dr did that for me - the progesterone just as a 'in case' that was it. I was told I should take the baby aspirin every day of my pregnancy. Good luck to you.
I agree with Diane1003 I would talk to you OB about taking childrens dose of aspirin daily until 12 weeks also if you have had 2 previous miscarriages I would ask to be put on a progesterone supplement as soon as you find out your pregnant until 12wks. Low progesterone is the number one reason why women miscarry.
I had two miscarriages back to back about a year and a half ago. I hadn't ever really noticed anything with my periods -but occassionally there would be clots. After testing it was found I have a blood clotting issue for which I was told to take baby aspirin. I went on to have a healthy pregnancy and have a healthy son. Have you had any testing done - has your dr said anything about taking baby aspirin?
