Re: CB Fertility Monitor,
For me i think using those cheap OPKs and CB Smiley face is more then enough le.
Tho the monitor will tell u is your peak then u bd. I thk its the same as just before u test positive using OPK and bd.
I usually use cheap OPK to test twice a day and on the positive day or really near positive then i use the smiley face to confirm.
If u r those with very regular cycle den i thk dont need cuz u will O roughly e same day each cycle. If really accurate kind, u will O on that particular CD. So it really defeat the purpose of buying the monitor.
Some more the monitor not everyone will buy so next time if u strike and wanna sell off also hard.
Well, thats my point of view la. I rather spent the money on tcm. Invest in smiley is good enough. Personal preferences la.. =D
Alternatively, u can look for those mummy who has graduated and they r selling their monitor. =)
