fertile as a garden???

I had bought preseed an had planned to use it but my fiancee referred to me as being "fertile" with our first baby we only had sex once and bam! I was pregnant. now that I had my birth control removed and we are trying for a second he says I don't need to try all those hacks meaning OPK's, preseed, and laying on my back for a certain amount of time once we're done. He says I will get pregnant fast like I did last time but this time is taking a little longer. He says to me "babe youre as fertile as a garden". Ugh I wanted to punch him
