Okay so talking to Dr. Higby - the high risk specialist - yesterday he gave me the following information:
Topical substances are not at issue. He said that all of my possible sunscreens are fine.
Talking to my regular OB today, Dr. Garcia-Hodge, I asked her yet again about sunscreen and she vehemently told me that I should not use anything with any of the stuff mine have in them and ONLY something that has just zinc oxide and NOTHING else. When I explained about what Dr. Higby said she was freaked about his response. However, since he is the one who deals with high risk cases every single day I'm going with his reply.
Also I asked my friend whose father is one of the top OB people in the world (he is who people go to for training in specializations) and she informed me the same thing as Dr. Higby.
