Hi. Sorry you're having so much trouble.

Firstly, have you tried using the symptom-thermal method of tracking your cycle? Fertility Friend is a good site to learn how, otherwise some books like those by Francesca Naish have a good explanation. I find temping reduces the guess work. If you start now, you may have a better idea of what's going on by your FS appointment.

Secondly, you may have a hormonal imbalance. I've found acupuncture very good at sorting this out.

Thirdly, nutrient imbalance can affect our hormones/fertility. It is worth checking your levels of zinc, magnesium, iron, vit d, c & b. a naturopath would be able to advise you better. Diet, exercise and sleep all contribute to health & fertility as well, so worth looking at.

I hope you find some answers soon.
