Your cycle is typical of a PCOS related cycle and I am not surprised to see that you have been previously diagnosed with PCOS. I would also think that you have ovulated very infrequently during this time if at all. Usually most cycles over 35 days are anovulatory in nature. However, some women with PCOS can ovulate spontaneously but its usually on an infrequent basis.
Unless ovulation was confirmed by blood tests you cannot assume that ovulation actually happened. Clots can be related to the cycle length and are part of the endometrium lining; such things can more often occur after a very long cycle as the lining builds up.
PCOS should be carefully managed by a gynae particularly when it comes to ttc as many women with PCOS will require some medical help in order to conceive.
PCOS is a very individualistic disorder and affects each woman with it very differently. What may be a problem for one is not so for another.
Generally speaking as a fellow PCOSer I would try and stay within the correct weight range for your height as excess weight can exacerbate symptoms.
Your GP should refer you to the specialists at the hospital subfertility unit as a matter of course. This is not a condition that should be messed around with by GPs as they cannot monitor you properly.
