I applied polysporin complete with 3 antibiotics + 1 analgesic (the black one). I read this morning that it is not recommended for pregnant women and now I am stressed. Is it serious?

If you have applied the ointment a few times, there is no need to worry. However, it is best to avoid using it from now on. It is normal for the skin to be red as it is a sign that the body is healing itself naturally. Avoid applying anything on the area and let your body's natural defenses take care of it.
