Hi fruitloop
First and foremost(((((((((fruitloop)))))))))
I would actually try and see another gynae ; some of the info you've been given I would query further (you do not need a regular cycle to take clomid; this is often prescribed for anovulatory cycles). They could also do internal ultrasounds as well as blood tests to see whether your ovaries are polycystic.
Northisterone to bring on your period - hmm why not provera instead?. I would query this anyway. My periods were pretty much non existant when ttc and the unit I was at never gave me anything to bring on a bleed.
Blood test re LH and FSH - that's fair enough on their part. Make sure they compare the level of LH against FSH!.
HSG is a useful test to have done as it is a tubal x-ray. Deformities INSIDE the tube can only be seen by such a method. You will be fully awake for this procedure; it is not the same as a lap and dye (this is basically the dye without the laparoscopy which is keyhole surgery). Have had a HSG myself and did not use either of what you've been told to use the days before. Was also not advised to avoid intercourse before HSG.
7th July is waaaaaayyyyy too far away, you need to be seen far sooner than this, both regularly and monthly. I would ask your GP to refer you to another unit as regularity of appointments and continuity of care is vitally important (you should be seeing the same people each time).
You should not also have to postpone your wedding day.
Re the semen sample he will need to do this and likely have it repeated. One semen analysis alone is not conclusive of there being any male factor problems (hence repetition).
Temp can rise during the second half of a cycle when an egg has not been shed. This is why I would not use temp charting if PCOS is suspected.
I hope the above has helped a little, I certainly do not want to make you feel any worse.
Any questions just ask
