Cuddlepie, the aspirin is simply going to thin the blood - something the clexane is already doing for you. I'd be inclined not to worry about it - especially as you already have something to prevent clots and your FS says not to.

I was guilty of self-medicating aspirin. But my FS refused to admit that there was a problem, despite three miscarriages - two of which were very early. I was already on prednisone for arthritis and possibly NK cell problems, and had borderline results with lupus anticoagulants. It was on the advice of the woman I saw for acupuncture after first confirming with an OB that it would do no harm if I took it but didn't need it. I started the day after EPU and the cycle where that was added was the cycle that resulted in my first successful pregnancy.
