I too take cardiprin but will be stopping under Dr's orders at 34weeks, so just a couple of weeks to go for me. Had taken low dose aspirin (cardiprin) with my youngest two DD's as well. Have a talk to the pharmacist with what your DR wants you to take. I am sure they will point you in the right dorection. Or get your OB to give you the name of what he wants you to take, especially considering he will be your primary care provider during your pgcy. Have to say tho, the hospital was tossing up whether to put me on clexane injections this time round, yet thankfully the aspirin has worked well.
