Thank you for that additional information.
I can understand your concern. That being said, if all your physicians as well as your OB/GYN fertility specialist -- doctors who know you personally and know you well -- say that you will be fine then I would trust their expertise and believe that you will, and the embryos will, be just that -- fine.
Reading studies and talking to The Evil Dr. Google is enough to freak out anyone.
So. What should you do?
Believe in your physicians.
If you don't believe in them you should consider postponing the implantation and seek out another, in person, opinion with an expert (or team of experts) you can trust.....perhaps by going to a large Teaching Hospital and consulting with Professors who are at the top of their field. Medical Professors like this can be found, for example, at the Mayo Clinic in Rochester, Mn.
Does this make sense to you?
It's safe for you to press the positive feedback button now if you so desire. And, never fear, even after you press that button I'll still be right here to continue helping you, but, as I do work for tips, I want to make sure you are happy before rating me.
