I think seeing as its doing no harm in there in the mean time, just to leave it until you get back from your honeymoon, then get it removed and immediately start TTC.
there is no need to wait after having it removed before TTC. the only thing I was told is 'nothing in the vagina and no swiming/bathing for 7 days'
after mine was removed I cramped for a couple of days and bled for 5 days. I was immediately fertile and ovulated that cycle.
very quickly after removal I noticed my acne was returning and now (10months later) its worse than it ever has been.
