Hi hun! I have factor V Leiden, so was given baby aspirin to take til I was 8 weeks pregnant, then moved on to Clexane. I had absolutely no side affects at all, it's nothing to worry about! I'm taking baby aspirin again at the moment to help me to concieve again as it's supposed to help blood flow and thicken the lining of the uterus! They do say that Aspirin can reduce fertility, which is one side affect, but not at such a small dose! Hope all goes well for you x
