Increase in allergen sensitivity during pregnancy?

Wondering if anyone else has experienced this, and if so, whether it got better after delivery!  I've always had a mild allergy to my cats (like if I forget to wash my hands after petting them and then touch my face).  Since becoming pregnant, my sensitivity to them has gone through the roof to the point that I'm avoiding even touching them, which is leaving me feeling badly and them with cattitudes.  Now I gets welts on my skin if their saliva touches me and am sneezing constantly if I'm around them.  Fellow cat ladies (and other allergy sufferers), have any of you been in this situation?  Is there an end in sight?? ??
