So total newbie when it comes to this conception lark so this is probably a silly question but is a basal thermometer necessary for tracking temperature or will a regular one do?
DH and I, both mid-30s are battling our teenage belief that unprotected sex will automatically lead to a baby so we’re unsure just how much of the stuff peddled at would-be parents is necessary or whether we just continue getting it on and hoping for the best? 
Any advice would be gratefully received.
