I found this on a government website but not sure if I can post the link so am posting the quote...

GARDASIL? is not recommended for use in pregnant women. However, there is no evidence to suggest that administration of the vaccine adversely affects fertility, pregnancy or infant outcomes. If the vaccine is inadvertently administered during pregnancy, advice should be given to defer completion of the course until after the birth; there is no need to consider termination.
And this is from the gardasil product info:

During clinical trials, 2,266 women (vaccine = 1,115 vs. placebo = 1,151)reported at least one pregnancy. Overall, the proportions of pregnancies withan adverse outcome were comparable in subjects who received GARDASILand subjects who received placebo.Further sub-analyses were done to evaluate pregnancies with estimatedonset within 30 days or more than 30 days from administration of a dose ofGARDASIL or placebo. For pregnancies with estimated onset within 30 daysof vaccination, 5 cases of congenital anomaly were observed in the group thatreceived GARDASIL compared to 0 cases of congenital anomaly in the group that received placebo. Conversely, in pregnancies with onset more than 30days following vaccination, 10 cases of congenital anomaly were observedin the group that received GARDASIL compared with 16 cases of congenitalanomaly in the group that received placebo. The types of anomalies observedwere consistent (regardless of when pregnancy occurred in relation tovaccination) with those generally observed in pregnancies in women 16 to 26 years of age.Thus, there is no evidence to suggest that administration of GARDASILadversely affects fertility, pregnancy, or infant outcomes.
I hope this helps allay your fears.
