the good thing to keep in mind with it comes to OPKs compared to temping is that you can really compare them they do two differnt things.
OPKs tell you when you are ramping up to O
Pros:
- they give you a day or two warning, important mostly if you have wildly varing cycles and could burn yourself out BDing every other day for a very long time each cycle.
- they dont require good sleep patterns or disrupting a family bed
Cons:
- they dont confirm O, you can get positives and not O
- they dont work for everyone, some ladies never get a pos, some ladies get them for many many days
- they cost money each cycle
Temping, tells you when you actually O'd
Pros:
- actually confirm O and sometime other issues about your cycle
- one quick thing to do, free once you have a thermometer
- lets you compare cycle histories over time
- lets you possibly see when AF is coming
Cons:
- does not give you warning about upcoming O (except for past history which can certainly be all you need)
- required some amount of consistent sleep pattern and discipline with waking
- daily temps can drive you nuts until or if you learn not to fret about them
in the end what you do will usually depend a lot of your type of lifestyle and cycle.
if you have a basically regular cycle i think temping is better to catch little issues and let you know everything is going smooth and to let you know good due dates for when you do get preggo, with OPKs only being needed if you need to time a insem or something like that.
if you have wildly irregular cycles and you have seen opks work well, then they can really help you narrow things down so that you dont burn your lovemaking good will out, but i still think temping is good to have as well to confirm things actually happened
ok i'll stop babbling now
