Progesterone is (initially) produced by the corpus luteum, that is the so-called "yellow body" that forms in your ovaries from a follicle that has launched it's egg. If your progesterone levels remain low, I might still be concerned about whether you ovulated properly. Clomid may hep to make you ovulate by increasing LH and FSH levels, some women have found it successful. But it doesn't directly elevate progesterone levels.
You might consider trying to tackle the root of the problem - insulin resistance - rather than tackling the symptoms (lack of ovulation). There are a number of things you can do to get your body to ovulate naturally and to re-balance your hormones:
(1) Adopt a low gylcemic index diet. This means avoiding foods that give rise to a rapid increase in blood glucose levels. This in turn reduces your insulin levels. You can find info on the web, a couple of examples are

(2) You should make sure you eat foods rich in d chiro inositol or "dci". This is a natural compound that mediates insulin production and has been proven in clinical trials to help in PCOS. The target should be 600mg of dci per day (or 1200mg for women with BMI over 30). Buckwheat flour ("farina") is the richest source but there are many others. Chick peas are good if you like hummus. Please see the links below. Not included in the links, but more commonly available in Asia, are bitter gourds (aka bitter melons) and shark fin melon (aka fig leaf melon or fig leaf gourd).

(3) If your BMI is over 25, then you should work hard to get it below 25. Exercise regularly and control your calorie intake if this applies.
Good luck
