i wouldn't worry about it, though i know it's stressful. Before i found out i was pregnant with this one, i was drinking some alcohol here and there, but this baby's fine

Because you had these treatments before you even knew you were pregnant, i wouldn't worry. the amount that would have actually gone to baby would have been very minimal, and even then, organ formation and all that doesn't start properly until 5 weeks or so, which by then you had stopped taking the cream. So don't stress, everything should be fine. Babies are surprisingly resilient
