Help! Aspirin for implantation. Really need to know what to do!

Kendra • Happily Married!! Two beautiful little girls :)
I had a Chemical in October. I was told by a friend to take aspirin for implementation. So I googled it and found that a lot of women done it and a lot of OB's recommend it! It had a big success rate. I seen a few women on here do it also. So I tried it and got a BFP my next cycle! :)) I'm also 8 weeks now and wondering when do I stop with the aspirin? It's a baby aspirin (81mg). Some I read ropes at second trimester and some I read took it the while pregnancy. I haven't seen my OB yet and won't till 12 so just liking for some info. Thanks!!
