Hello! I am the OP, but I have a different username now 
I'm sorry to hear that you're having similar problems, it's really rubbish.
To be honest, I'm a little hazy on all of the details now, but I'll fill you in as best I can.
So I saw a gynaecologist, who said that the cyst wasn't large enough to need removing, but that the ovary wasn't working and wasn't releasing an egg as it should. So they referred me to the fertility clinic and I had a hycosy which is where they inject dye into your tubes to see if they are blocked and preventing the egg from travelling- mine were fine. I also had a camera in my uterus to see if that was okay, and was diagnosed with a uterine polyp, which they wanted to remove. So I was booked in to have the polyp removed, but when I went in for the procedure, it had disappeared on its own. So then I was referred back to the fertility clinic. The fertility clinic said that we had had a low chance of conceiving on our own, so suggested we be referred for IVF. As this was for a second baby, we declined because at that point we didn't have the money to pay for it.
Fast forward a year, and we decided to go for IVF abroad, so we actually went to the Czech Republic
The clinic were amazing, and requested my husband to have some additional tests in the UK before we went there, which determined that not only did I have problems, but that also there was no way his sperm was going to work, and that we would need ICSI. The clinic abroad also diagnosed PCOS, which had been mentioned by UK doctors, but never confirmed. Anyway, 9 months later, we welcomed a little girl, who turned one a couple of weeks ago 
I hope this is in some way helpful. I am a little fuzzy on the details now I'm afraid, but essentially, that's how it all went since I posted about it. If you have any further questions, I'll do my best to answer them!
