When did you start...?

Je

When did you start using OPKs, fertility supplements, or pre-seed? My hubby and I just finished our first cycle TTC. I just got off bc a month ago and AF came right when expected so I’m still regular (I’ve never been irregular even before bc). I’m 27 and he’s 31. I don’t want to start obsessing over this but I want to get preggers before Xmas! Thoughts...??
