Gosh, I took it the whole way through my pregnancy with DD because of terrible hayfever and sinus issues. I was never told by my GP, OB or pharmacist that it wasn't safe in the last trimester. DD was just fine. One of my best friends was the same and no issues with her son either That's the first I've heard of it being risky in the third tri, I'd definitely be double checking that with your doctor instead of Google
