My suggestion to you would be to seek medical advice asap (your GP should refer you to a gynae).
Although it is possible to conceive without any medical intervention many women with this condition do require help of some sort.
I have also heard the implication that pregnancy will solve the PCOS problems - I do sigh when I hear women being told such things. It is more recognised these days although some docs still do not know very much if anything at all about PCO.
PCOS is a very individualistic disorder that affects each woman with it very differently. The causes of same are not fully understood although there may be some genetic factors. It is not a condition that ever goes away (and no one therapy or treatment will cure PCOS as the cystic follicles associated with it do return over time) but it can be controlled. Would suggest you try to stay within the correct weight range for your height as excess weight can excerbate PCOS symptoms.
It is little point in temperature charting with this condition as you could end up with a chart akin to the Rocky Mountains. Such charts are notoriously difficult to interpret accurately. Another problem with them is that you can have a temp rise in the second half of your cycle when an egg has not been shed.
The surest way of knowing whether you are ovulating or not is to have blood tests done. Having PCO/PCOS anyway means that regular ovulation is less likely to happen.
Would not suggest you use opk's either as these measure LH hormone. As many PCOSers have an excess of this hormone to start with the kit will only read this excess.
The cystic follicles associated with PCOS do disappear over time (this may be why scans of ovaries have been clear) only to be replaced by further cystic follicles.
Metformin can be beneficial to PCOS patients especially if there is insulin resistance (seen in some but not all PCOSers).
Verity is a very good UK based organisation specifically for women with PCOS, their web address is www.verity-pcos.org.uk.
Knowledge is power - the more you are aware of what PCO or PCOS is the better off you will be when it comes to making treatment decisions.
