Well, if it were me, I'd throw everything at at! Hey! Look! I am throwing everything at it. Well, barring major weight loss and dietary alterations - at the moment I seem to be ovulating fine and I'm off caffeine and alcohol so that's a start. Oh and you're taking your pre-natal folic acid aren't you
The thing about the ovulation sticks or monitors, used on their own it can create quite a lot of doubt. You may not find it easy to interpret the sticks, or you might get days and days of 'highs' on the CBFM, and without taking temps or monitoring CM, it's hard to know what to think. Likewise, temping can be a bit of an art so having the 'science' back you up can be helpful. That's my justification for it anyway.
The biggest thing you need to watch out for is the fertile quality EWCM, that the biggest signal that you're in right zone for ovulation and you pretty much want sperm up there ready and waiting for when the egg makes an appearance. A CBFM will give you 'high' readings, when it sees a rise in your estrogen levels - which should then provoke a luteinizing hormone surge, which is what the OPK sticks test for and shows up as a 'peak' on the CBFM. At some stage, normally about 24-48 hrs after the peak, the egg will be released, and be ready for fertilizing. When the egg has been released, your levels of progesterone start rising and that causes your temperature to rise, i.e. AFTER ovulation. That's a pretty good signal that things happened they way they should, you ovulated and and the EWCM dries up.
Then you get to either stop temping and wait for period or a +ve test. Or keep on temping and obsess about whether the temps are falling (reflecting a decline in progesterone and leading to a period), or staying up signalling possible success and a +ve test!
Anyway - it's up to you. And to make it even more fun, there are special threads for those who chart and those who pee (some go on both!)
Fingers crossed your 5dpo twinges are significant and that you're successful quickly. By the way, if you see a poster called mummyabroad around, wave and tell her your success story for Ashermans treatment. She's about to go for surgery and will be thrilled to hear that you conceived quickly after the coil was removed.
