So this month is about to come to a close (AF due 4/10) and I'm thinking I will be out. We barely BD'd this month (thanks to moving!) and I tested this morning and was negative. Also no symptoms whatsoever. In the interest of kicking off next month a little more enthusiastically, I want to up my game and add either temping or opk's to be more sure of my O date (til now just been tracking CM). What should I try first? Or should I go all in and try both? If OPK, do you all have a brand that you prefer to use? Thanks so much!
