Hi!
Many people would recommend that you take a baby aspirin (81 mg) daily prior to conception. If you do conceive, and begin heparin, you should certainly notify your MD that you have been taking the aspirin, and re-evaluate whether to continue or discontinue.
Also, you may wish to have genetic analysis done on the pregnancy products if you miscarry again (I sure hope not!) or on yourself and partner. It certainly could be that the Factor V is the whole issue, but many people with Factor V conceive and carry naturally too, so there could be more to it.
The other thing that I would do, if you were my patient is either a progesterone level or progesterone supplementation or both if and when you conceive. It won't hurt anything , and it may help. Also, you are probably aware that you should never use oral contraceptive for birth control, but I just had to throw that in there!
Good luck!
