Working on TTC #2 here and I have very irregular cycles so I was thinking about getting one of those fertility monitor things to try and pinpoint my fertile days. Last time around it took me nearly 2 years to conceive successfully. What finally worked for us was using PreSeed and doing the TTC every two days thing. We have less time on our side this time and a toddler interrupting sleep etc so I just feel I have to be more 'focused' this time!
Anyone used these and found them helpful or are they a waste of money? They are quite expensive so don't want to shell out unless they're worthwhile...
