let me try to clear some points regarding acne
Acne can be cleared or get worse in pregnancy so there is a mixed approach.
Secondly,generally as i can see in practice that acne get worse in the first few months of pregnancy but as the pregnacy proceeds it get better may be due to hormonal
Now if your cream has got Clindamycin
then i would say you can apply.
but i would also recommend the following
1:Benzoyl or Azelaic acid creams preferebly
2:DO NOT apply any creams that contains retenoids or salicylic acids.
Thanks very much and all the best.
