So I would not take Allegra as it is a category C drug. Zyrtec and Claritin are both safer at category B. All allergy medicines though cause drying and can dry up your cervical mucus to make it harder for the sperm to pass through to the uterus. But if you need the meds you need them!
And just to clarify, here is what the categories stand for!
FDA PREGNANCY
CATEGORIES
The FDA-assigned pregnancy categories as used in the Drug Formulary
are as follows:
Category A
Adequate and well-controlled studies have failed to demonstrate a risk
to the fetus in the first trimester of pregnancy (and there is no evidence
of risk in later trimesters).
Category B
Animal reproduction studies have failed to demonstrate a risk to the
fetus and there are no adequate and well-controlled studies in pregnant
women.
Category C
Animal reproduction studies have shown an adverse effect on the fetus
and there are no adequate and well-controlled studies in humans, but
potential benefits may warrant use of the drug in pregnant women
despite potential risks.
Category D
There is positive evidence of human fetal risk based on adverse
reaction data from investigational or marketing experience or studies
in humans, but potential benefits may warrant use of the drug in
pregnant women despite potential risks.
Category X
Studies in animals or humans have demonstrated fetal abnormalities
and/or there is positive evidence of human fetal risk based on adverse
reaction data from investigational or marketing experience, and the
risks involved in use of the drug in pregnant women clearly outweigh
potential benefits.
